Author: Ivan Baranov

Hello! I have a Lada Kalina. The check engine light is on, but everything works fine. There is error 4 on the panel. What does this mean and what could it be related to? (Vladimir)

Hello, Vladimir. The appearance of the CheyEngin icon is a common problem in all domestic vehicles with an on-board computer. Tips for solving the problem are given below.

What does error 4 mean?

Fault code 4 indicates that the refrigerant temperature control regulator is not functioning correctly. In most cases, this code lights up on the dashboard if, within 20-30 seconds, the electronic control unit detects a break in the regulator wiring.

Car Lada Kalina tuning

1. After analyzing your problem, we turned to many sources on the Internet and consulted with the owners of Lad Kalin. As it turns out, the number 4 often appears on the instrument panel, this can be considered one of the most common errors in these vehicles. Replacing the antifreeze temperature regulator in the cooling system in some cases will help cause the error to disappear. However, according to most potassium growers, in fact, in most cases it does not give a good result.
2. If you believe the reviews of car enthusiasts, then such an error, as a rule, appears mainly during cold weather. If there are no signs of breakdowns, then perhaps you have no reason to worry.
3. It is likely that over time the vehicle has been used, the sensor itself has oxidized. As a result, a poor contact is formed, which does not allow signal transmission in normal mode. Sometimes this happens after you have washed your car. We recommend that you carry out a visual diagnosis of the regulator - if you notice that the contact has really oxidized, then it needs to be cleaned.
4. If there is continuity, if cleaning the contacts does not help, you need to check the car wiring. It is quite possible that the reason for the appearance of the code on the device is a broken wiring or short circuit. In the case of a break, it will be enough to replace the wires or eliminate the cause of the short circuit.

If you have changed the sensor, replaced the wire and cleaned the contact, but the problem still remains, we recommend that you perform more detailed computer diagnostics. In domestic cars, it often happens that if the control unit does not work correctly, errors may appear on the screen that in fact do not exist. To understand this, you need to completely read all the codes from the on-board computer and then draw conclusions.

How to replace the coolant sensor

To work on removing the coolant temperature sensor, you need to remove at least part of the antifreeze from the system. The easiest way is to drain it from the radiator, but you will have to unscrew the plug on the cylinder block, since the sensor is located not far from this unit. Let's figure out how to drain the liquid from the system completely:

If your Lada Kalina has a sixteen-valve system with a cable-driven gearbox, then you will need to remove the starter before draining the antifreeze. If you do not do this, you will fill this unit with coolant. The starter is held on by three bolts, but before removing them you need to disconnect the wiring.

Once you have removed the fluid, replace the plugs. Now you can start replacing the sensor itself. Remove the wire block from it, if you did not do this to check, then unscrew the controller using a 21 key. In its place you need to install a new element, having previously treated the thread with heat sealant. Connecting the wiring to the new sensor is not at all difficult - the chips have special notches for proper installation.

Return fluid to the cooling system through the expansion tank. It is necessary to use new antifreeze; the manufacturer recommends using red “Felix” for this. Then reassemble, warm up the engine to bleed the system. Check to see if antifreeze is leaking from the plugs or through the threads of the sensor. After the engine has warmed up, touch the pipes - they should all become warm. If everything is normal, you can begin testing the system and making a test drive. If the error persists, then most likely the on-board computer provided false information.

Video “Do-it-yourself diagnostics of a Kalina car”

To learn how to properly perform computer diagnostics at home, watch the video.

VAZ Lada Kalina is equipped with a standard computer immediately at the enterprise. Moreover, it is a high-quality brand, has wide functionality, and can satisfy many car drivers. But for those who want more, it is recommended to purchase a device with serious functionality, for example, the Gamma on-board computer.

It has much more functionality compared to a standard computer. It displays and resets fault codes, and at the same time makes diagnostics. It is launched on the dashboard by pressing a key to reset the daily mileage, and at the same time turning on the ignition. After pressing the key, the firmware version of the on-board computer (BC) and error codes, if any, will be shown on the computer screen.

Diagnostics

If you notice that something is wrong with the operation of the Lada Kalina vehicle, then it makes sense to diagnose the car. As a rule, all breakdowns appear immediately after checking the car. You can ask for help in carrying out diagnostics at a service station, where you will pay a certain amount for this service, or you can do everything yourself. Of course, with the help of special equipment there is a greater chance of identifying a malfunction, since when checking independently there is a possibility of obtaining inaccurate data.

So, let's start diagnosing the car ourselves. For this:

To check your car for breakdowns, hold down the daily mileage button and hold it while turning on the ignition key. At this time, all arrows will go from zero to maximum. To read combinations of faults in a car, you will need the last screen. It will display clear codes. To obtain four-digit combinations of faults, use special equipment or the services of specialists at a service station.

Possible error codes Kalina

What error codes exist for VAZ Kalina?

1. The highest voltage on-board network of the machine.
2. Fuel sensor error (for example, within 20 seconds it was detected that the circuit was broken).
3. Coolant temperature sensor error.
4. The motor is overheated.
5. Oil pressure is in poor condition.
6. The brake system has broken down.
7. Battery low.

What should I do to troubleshoot? You should hold down the key and turn on the ignition, but do not start the car. The arrows on the dashboard will move and the lights will turn on. After this, you need to press one of the keys on the switch, which is located under the steering wheel. Then the arrows will be at the initial position, and errors will be shown on the display.

Let's give advice to those who buy a used VAZ car - most drivers don't even think about the fact that there is an option for diagnosing and resetting Lada Kalina errors. And therefore, before buying a VAZ, you should run this option to find out everything about the past of the car you are purchasing. The modern automotive industry is a very developed industry; it is almost always an excellent assistant to any car owner.

This does not depend on the make of the car; the presence of BC is an excellent feature of almost any car produced over the last ten years. A similar system is no exception for VAZ. Many people know what an on-board computer is, but not everyone knows how to evaluate errors that have occurred and determine their significance. Let's look at the above errors.

It should be noted that many of the errors characteristic of VAZ are understandable. For example, a temperature sensor error, the BC can issue it when the motor is cooled. But it happens that the computer gives an error falsely. For example, once the motor was overheated, the computer suddenly notifies about the error, even if there is none. That is, errors can occur if the BC remembers information about an overheated motor. And therefore, when this problem has been fixed, it is better to reset all BC readings.

And to fix it, you should press the Reset key - it is located under the control buttons of the on-board computer. But if the faults are not identified, you need to ask a professional for help. You should also pay special attention to the errors of the machine's bookkeeping system if it has already been used and was purchased secondhand.

Sensor check

Checking the functionality of this sensor is not difficult. But before you do it, it is advisable to check the integrity of the wiring going to it. You can also check the voltage coming from the control unit. To do this, you need to disconnect the chip with wires from the sensor and connect it to a voltmeter. After this, start the engine and measure the voltage supplied to the sensor; it should correspond to 5 V. If the voltage is normal, check the sensor for resistance.

Vehicle diagnostics and troubleshooting

If you nevertheless decide to buy a used car, then you should definitely make a diagnosis, paying attention to any Lada error codes that appear on the device display. Information about existing errors will be very useful, be sure to pay special attention to this. To diagnose and find out information, you should contact a car service center if there is no special insert on the used car you are buying.

In fact, such a procedure is a huge list of information that can tell about any possible danger. Usually this is not given importance, but in vain. For example, if a car’s BC states that the airbags are faulty, you definitely need to check this. Correction: what needs to be done? Immediately press the left button and the right one, from this press the on-board computer adjusts the selected parameter.

Then pressing the keys left or right changes the parameters. After pressing simultaneously, you exit from the adjustment. Reset. By pressing the left and right keys simultaneously, the options displayed on the screen will be reset. If everything is done in the “System error” mode, after that the error disappears. If faults actually exist, the error will remain in memory until reset occurs.

If the BC does not turn on, the causes of the problem are:

• there is no electric current in the BC connectors;
• there is no contact in the terminals.

BC cannot diagnose the reasons for this:

BC cannot calculate the speed of the car, the reasons for this problem are:

• there is no contact in the connectors.

BC cannot calculate the remainder in the fuel tank, reasons:

• devices do not have software compliance.

The BC incorrectly shows how much fuel is left in the tank, the reasons for this are:

• there is no wire in the wiring at the 8th contact and the 9th terminal in the on-board computer;
• The car panel is showing incorrectly.

There is no BC screen backlight, reasons:

• I need to make the screen brighter.

The thermometer shows incorrectly, reasons:

• the wire has broken in the temperature detection sensor;
• incorrect contact with the on-board computer.

No voice accompaniment, reasons:

• speaker is faulty;
• the software has crashed;
• The voice accompaniment is not reproduced (you must press the “up” key and hold it for more than three seconds).

BC writes incorrectly, the program has gone wrong, etc., reasons:

• The on-board computer is not connected or there is no contact with it;
• there is no contact in the connected battery terminal (the contact should be securely fixed).

Initialize the BC:

• previous settings will be reset;
• reset all parameters for the previous ride;
• set the clock to 8 hours 00 minutes;
• The alarm clock should be at zero, its notification is disabled.

Replacing spark plugs and high-voltage wires

Spark plugs in a car are the main components for igniting the fuel mixture. If the spark plugs are faulty, the spark will not be supplied correctly to ignite the gasoline mixture. Faulty spark plugs often result in a lack of spark or an incorrect spark interval, which results in the engine not running properly. If the spark plugs do not work properly during acceleration, especially from a standstill, you may feel slight jolts.

What are the reasons for spark plug failure: Most spark plugs in cars produced before 1996 need to be changed every 25,000-30,000 kilometers. In newer cars, spark plugs last more than 150,000 km. However, these scheduled spark plug replacement intervals may be reduced by various factors related to fuel quality and driving style.

What needs to be done: If your spark plugs have not been changed for a long time, or you feel failures in the engine operation associated with ignition, then you must immediately replace them with new ones without delay. Do not try to save money by untimely replacement of spark plugs, since the cost of spark plugs is not very expensive, as well as the work of replacing them. By replacing old spark plugs, you will improve engine performance and reduce your vehicle's fuel consumption. Changing spark plugs yourself is quite easy. Basically, they are easily accessible under the hood of the car. You need a regular spark plug wrench to remove the spark plugs from the engine. It is also advisable to monitor the condition of high-voltage wires, since over time they can become unusable and allow electricity to pass through, which is transferred to the spark plugs, which will reduce the strength of the spark. Remember that regularly replacing spark plugs, in accordance with your car’s maintenance schedule, protects your exhaust catalyst from breakdowns and also improves engine performance!

Deciphering codes, checking devices

Mistake No. 2. Overvoltage. Error No. 3. An error has been detected in the fuel sensor level; it occurs if the circuit is broken.

Error No. 4. Coolant temperature sensor error. Error No. 5. The outside temperature sensor has failed. Error No. 6. The motor has overheated. This happens if the engine overheating alarm is triggered. Mistake No. 7. Oil pressure is in poor condition. Happens if the alert bell is triggered. Mistake No. 8. Problems with the brakes. Happens if the alert bell is triggered. Mistake #9: The battery is dead. Happens when the alert bell is triggered.

To reset all types of errors, press and hold the reset button until all data on the display is cleared. Testing of devices and their combinations is carried out in accordance with technical specifications using special equipment (pulse generator, from a stable power source, etc.). If a short circuit suddenly occurs in existing devices (less than 40-50 Ohms), the maximum temperature indication must prevail.

The devices operate from an electronic module, which receives signals from various sensors. The tachometer and speedometer are powered by stepper electric motors. The electrical instrument cluster cannot be repaired. The daily mileage of the car can be set on the 0 key, which is located on the right. The meter and its readings are saved when the battery is disconnected. That's all. Good luck!

According to the service manual, error number 4 in the control unit indicates a malfunction of the coolant temperature sensor. According to reports from members of our community and according to motorists, this error is quite common and appears often on the Lada Kalina. It’s worth figuring out why errors pop up and how to fix the problem.

Self-diagnosis of the Kalina/Priora instrument cluster

1. With the ignition off, press the “Reset” button (reset daily mileage). While holding the button, turn on the ignition.
2. The instrument panel will go into self-diagnosis mode, all segment positions will light up on the display, all indicators will light up, and the arrows will travel the full path.
3. Using the control button on the right steering column switch, we switch between modes (self-diagnosis, firmware version, error codes).
4. To reset errors, you need to be in error mode and press and hold the “Reset” button for more than 3s.
5. The diagnostic mode exits automatically after inactivity for 20-30 seconds.

Decoding error codes in the dashboard:

• 2-increased voltage of the on-board network;
• 3-fuel level sensor error (if a break in the sensor circuit is detected within 20s);
• 4-error of the coolant temperature sensor (if an open circuit of the sensor is detected within 20s);
• 5-outside temperature sensor error (if there are no sensor readings within 20s, indication on the LCD is “-C”);
• 6-engine overheating (the criterion for triggering the acoustic alarm has been met);
• 7-emergency oil pressure (the criterion for triggering the acoustic alarm is met);
• 8-defect of the brake system (the criterion for triggering the acoustic alarm is met);
• The 9-battery is discharged (the criterion for triggering the acoustic alarm is met);
• E-determination of an error in a data packet stored in EEPROM.

How to reset errors on Kalina? You can reset the errors yourself using the on-board computer, or contact a service station with special diagnostic equipment.

Let us remind you that detailed photo reports can be found in the Lada Kalina repair category.

Causes of 4 errors

Error 4 came on on the on-board computer screen ( marked with a red arrow )

There are several reasons why error 4 appears in the ECU. Let's consider all possible options:

The coolant temperature sensor has failed.

In the process of replacing and repairing the coolant sensor on Kalina

Checking the wiring and voltage supply to the sensor

All of these reasons are fairly easy to fix and are not a cause for serious concern.

How to view errors on the on-board computer?

The video shows the “self-diagnosis mode” of the Lada Kalina car, in which you can find out if there are any errors:

Elimination methods

In order to eliminate the cause of error 4 in the Kalina ECU, you should perform the following operations:

1. Check the sensor for functionality. If it “died”, then it should be replaced.
2. Check if there is contact and if there is any plaque. Clean the seat and replace the sensor.
3. Check the on-board circuit and make sure there is contact in it.
4. But a random error will have to be treated only by flashing the ECU and resetting all errors. To do this, it is recommended to contact a car service.

Thus, you can solve the problem yourself, but as practice shows, this does not always work out. Error 4 occurs quite often in the cold season, when the car is parked in the fresh air for a long time, and not in the garage.

How to reset errors?

Upon completion of self-diagnosis, errors must be reset. How to perform this action can be found in the corresponding recommendations of the car manufacturer. In practice, it has been established that the reset procedure is identical to the manipulations to launch a new system check. Here the controllers are reset and the reset itself occurs, which is provided by special software tools present in the ECU software. The procedure is also performed during the next service in case of characteristic malfunctions. For example, code “0171” may be displayed with annoying consistency, indicating low-quality fuel in the LADA Kalina car system of the same name. This should alert the owner to changing the refueling location. Owners also consider “1545”, “0422” and “1426” to be common errors.

conclusions

Finding and eliminating the cause of error 4 on the Lada Kalina turned out to be quite easy. Although deciphering error codes requires special knowledge, the necessary information can be found in this article.

As in any electrical/electronics, there are no miracles, only bad contacts. If there is a sensor malfunction, then there is a circuit from the sensor to the computer. There is a malfunction somewhere.

I have a Kalina 1118, as described in the article - this is a common mistake on viburnums, but I have never had one like this, not even my friends. I myself have installed the Delta CEP, all errors are clearly described and it is not difficult to find a solution on the Internet.

Everything is written correctly. But everyone forgets what a gigantic percentage of parts are defective. Personally, only the third sensor from the store worked for me.

Error 4 appeared occasionally a couple of years ago. Then it disappeared. For the last year it has been on constantly. But nevertheless, the device on the panel shows the temperature correctly... I tried to remove it, it lights up again and again... I gave up on this matter and just drive on... All systems work fine and ok... I tell everyone that it is on because it works engine…

There are two temperature sensors in Kalina and the one that gives readings to the tidy is located a little lower than this one, which is discussed in this article...

the device on the panel (arrow) is controlled by another sensor

Perhaps the wiring connected to the sensor has broken, and hence the emergency mode with increased fuel consumption.

I have the same problem. But here's the pies... I checked everything, the whole system is working, the sensor was replaced, the fan works when it heats up. But the check is on. I'll probably have to flash it...

We forgot another option for this error to occur, it is a bad mass, or rather a parasitic influence on the computer on board due to mass from other systems. In the harness that goes to the computer there is a twist of masses, they need to be untied, as you look for on the Internet.

Hello, Vladimir Did you have such a problem when the engine overheated above normal? I changed the thermostat, pump, cylinder head gasket, but the problem does not go away.

It pops up periodically......I remove the negative terminal for 2-4 minutes. True, you have to restore the settings of the clock and radio. But in general it can be jammed... if the cooling system is working properly

For the third day now the check light is on, it shows error “4”, I reset it, then reset the terminal, but it didn’t help, it’s still on

Masses see 100%

You need to connect through the test connector and look at the real code, for me the error on panel 4 turned into code P0343.

Good afternoon, evening, morning, whatever suits you. I would like to share a little information that I have thanks to the use of a Kalina car with a simple 8-valve engine. Once... or twice... or a season... in general, I encountered a popular problem that spoils the mood of many - the car “lived its own life.” The revolutions do not float like a child. While you're driving, it seems like nothing, but if you stop at a traffic light... there's a guard. She herself holds one and a half thousand, two, two and a half. I tried everything. First, I changed two sensors at once - dhx and dpdz. Nothing changed. Then I bought the same sensors only from a different manufacturer, in the hope of thinking that they were defective (both two and only I got the fool) in general, it didn’t help either. I went to different auto specialists (we have two in total), did diagnostics, just don’t forget to fix it, as they say. I even changed the firmware. Everyone threw up their hands! And the car continued to live its own life... Then, out of my mind, I changed all the sensors in a circle, including even the DMRV (the most expensive one). But nothing has changed. I was desperate. For two months this problem bothered me - you fly on the highway, it twitches; the consumption is crazy; you drive around the city and everyone shys away from you... I started sinning on the computer... Probably the khan came to him since the problem was global, but there were no errors!))) (I’m smiling now, then I wanted to cry). Issue price 11

Decoding combinations

Errors read on the standard panel of the on-board computer can be deciphered using the table. It is useful to print out such information and carry it with you in the glove box, since breakdown of car sensors can happen on the road. Many problems can be corrected only during repair work in a car service center. Knowledge of the decoding will allow the owner to control the process of repairing his car.

Self-diagnosis codes

When diagnosing, you can read the fault codes listed in the table from the instrument panel. Please note that several errors may be displayed simultaneously during the verification process.

Below is a complete list of self-diagnosis errors.

Code on screen	Decoding
2	Excess voltage in the on-board electrical network
3	No signal in the circuit from the fuel level sensor
4	No signal from the internal combustion engine temperature sensor
5	The signal from the sensor measuring the air temperature outside the car is not detected
6	Raising the engine temperature above the permissible level
7	Critically low oil pressure in the engine lubrication system
8	Brake fluid leak or failure of the system's electronic components
9	Excessive reduction in battery voltage
E	EEPROM data error

Controller errors

For more complete diagnostics, the car needs to be checked with a KKL VAG-COM for 409.1 scanner. To do this, you need the scanner itself and a laptop with the pre-installed Diagnostic Tool v. 1.3.1., which allows you to view all the vehicle’s operating parameters and find out possible problems. Error codes received by such devices will consist of four numbers and a letter located in front of the numbers.

It should be remembered that each letter is responsible for a certain part of the machine components:

• B - indicates errors in the electronic components of the car body (window lifters, microclimate);
• C - errors in chassis components (power steering);
• P - malfunctions in the engine or automatic transmission control systems.

The video, shot by the author of CompsMaster, clearly demonstrates the connection of a test laptop to the diagnostic connector and shows the functionality of the program.

Another way to control the ECM is the additional on-board computer State, which is connected directly to the diagnostic connector and installed on the center console. This device is capable of reading almost all operating parameters of various vehicle systems. There are several types of State computers, which are selected according to the model of the ECM unit.

CAN bus errors

On the Lada Kalina 2, several specific errors in the CAN bus operation are often encountered.

The main ones include:

• U0001 - general CAN bus malfunction;
• U0009 - short circuit of CAN bus components;
• U0073 - CAN shutdown;
• U0100 - no communication between the ECM and CAN;
• U0155 and U0305 - errors in interaction between cruise control and CAN bus.

EMUR errors

Kalina cars are equipped with an electromechanical power steering (EMPS), during which errors with index C are common.

ABS errors

In the chassis of modern Kalina and Kalina 2, equipped with an ABS system, the following category C errors are often encountered.

Code	Decoding
0035, 0040	Failures of speed sensors on the front wheels
0045, 0050	Similar, but on the rear
0060, 0065, 0070, 0075, 0080, 0085, 0090 and 0095	Damage to valves in the anti-lock braking system module
0161	Stop light doesn't work
0550, 0640	ABS control unit memory errors
0800	Low voltage in the ABS block circuit

Airbag errors

Many Kalinas of recent years of production are equipped with airbags that have their own control units. They are characterized by errors with index B.

Code	Decoding
9000	Control unit error
9001, 9002	Malfunctions in the driver and front passenger seat belts
9003, 9004	Front airbag failure
9042	Incorrect power settings

Errors of light, mirrors and others

In addition to those listed above, we can highlight a number of errors in the light control unit, which is installed on some Kalina cars:

• In 9501 - there is no signal from the raindrop sensor on the glass;
• In 9502 - the sensor sensitivity regulator does not work;
• In 9503, 9505 and 9506 - errors in the functioning of the windshield wiper;
• In 9504 there is a problem with the operation of the headlight relay.

If you have heated and electrically adjustable rear view mirrors, additional errors are possible:

• In 9244, 9246, 9247, 9250 and 9251 - malfunctions of the mirror tilt system;
• B 9230 - error in the mirror control unit;
• In 9252 - sticking of the regulator contacts.

As a separate block, you can consider controller problems related to the operation of electrical equipment on the body and in the cabin. Such errors are indexed B.

Code	Decoding
0001-0004	Turn signal lamps do not work
0005-0018	Various problems in the operation of window motors
0019-0026	Problems with power supply to mirrors
0027-0028	Malfunctions of fog lights
0035-0038	Open circuit or overload
0039-0043	Breaks in the glass heating circuits, side lights and low beams
0044-0046	Immobilizer errors
0052	Error that appears after a power failure
1375-1378	Air conditioner evaporator sensors do not work
1382-1385	Open circuit in the interior temperature sensor circuit
1860, 1861	Power parameters are out of tolerance

In addition, one of the most common errors on the Lada Kalina is P 0441, indicating an insufficient volume of air supplied to purify the absorber. This problem causes the check lamp to come on after prolonged driving and does not affect the driving performance of the car. Malfunction P 1602 is no less common; it signals a loss of voltage to the ECM and is recorded in memory after the battery is disconnected.

Errors in lambda probes and their heating systems are common. For example, 0036, which indicates a failure of the electrical heating of the sensor. The solution to this problem is to replace the sensor or install a decoy. As changes are made to the design of cars and new options become available, the list of error codes for the Lada Kalina is constantly expanding.

Carrying out diagnostics on Lada Kalina

When the usual operation of your own car begins to be accompanied by the appearance of problematic symptoms, and various types of problems arise, then you should think carefully about how important it is at the moment to carry out diagnostic measures for all systems.

It is always useful to remember that you can always use a standard connector, since not every car has special devices that allow you to work with a professional and specific connector.

• It is very important to analyze code combinations, since in this case both the problem itself and its location are clearly represented by displaying a message on the monitor.
• This is a good help for the car owner, who can then carry out the appropriate replacement or repair. A scanner is attached to the connector for convenience. It makes scanning the problem the most extensive and detailed.

How does the self-diagnosis complex work?

This system is self-regulated in automatic mode. Its structural composition includes several electronic devices. Based on sensor impulses, a variety of information flows into the ECU memory, among which there are faults. They are presented in the form of designated fault codes. Car manufacturers do not support the idea that owners are inclined to independently maintain electronic systems of cars, therefore they tend not to disclose the meaning of the codes. Here we can see the noble motive of the developers, because they understand that in this way scammers can take advantage of the situation and change the settings of the electronic module, for example, reduce the odometer readings before selling the Lada Kalina car, etc.

This situation forces the manufacturer and dealers to persuade owners to service the self-diagnosis system in specialized services.

A particularly important component of this system is the on-board controller. With its help, information collected from sensors is processed and displayed on the display. Lada Kalina does not have such a device, which deprives the owner of the ability to visually read information regarding breakdowns. This is where scanning equipment comes to the rescue. Thanks to it, self-diagnosis occurs.

Broken fuel tank seal, catalytic converter failure

If the check persists on the dashboard, the car owner will look for a problem with the engine. But the reason may be different. The check engine light may come on due to problems with the tightness of the fuel system. The fuel filler cap may not be securely closed. Why does this problem occur? The reasons may be the following.

1. If the seal of the fuel system is broken, air begins to flow into it.
2. Additional fuel consumption appears.
3. Air in the fuel system causes engine problems.
4. The check engine light comes on on the dashboard.

How to fix the problem? If the check engine light is on and there are no signs of loss of power, knocking, humming or squeaking, then you need to check how tightly the gas tank is sealed. Sometimes, in a hurry, the driver simply forgets to close the lid tightly, or cracks begin to appear on it. If you have fixed the problem, but the check continues to light, then this is not the reason.

What to do if the catalyst fails? A car catalyst is needed to neutralize exhaust gases. The oxide contained in exhaust contains many substances that are harmful to the environment. The catalyst reduces the damage that a running vehicle causes to the environment.

If the check light is on due to a faulty catalyst, you will notice that the engine power has dropped significantly. The car loses acceleration dynamics. What is the reason for catalyst failure? Regular technical inspection of the vehicle will ensure that such a malfunction does not occur.

One of the reasons for catalyst failure is a breakdown of the oxygen sensor. Old spark plugs can cause catalytic converter failure. You should not take this problem lightly. If the oxygen sensor or spark plugs malfunction, the process of neutralizing exhaust gases is disrupted.

As a result, carbon monoxide begins to accumulate in the catalyst, it overheats and may burst. You cannot drive a car with a faulty catalyst. This will lead to improper operation of the engine, which is why the check light will light up. The car will consume more fuel and the engine will not produce traction.

The cost of a new catalyst is quite high, but still cheaper than engine repair. There is one more problem. You are unlikely to be able to replace the catalyst on Kalina yourself, so you need to go to a service center. To avoid this, you should regularly change the oxygen sensors and spark plugs.

The mass air flow sensor monitors air consumption. If the engine malfunction light comes on, you need to check the sensor. It monitors the amount of air required to ignite gasoline. Information from the sensor enters the on-board computer.

If the mass air flow sensor fails, the car begins to consume more fuel. There is a greater emission of carbon monoxide, engine power and the smoothness of the vehicle are reduced. If there is weak dynamics during acceleration, then it makes sense to assume that the sensor is faulty. As a rule, in cold weather the car begins to have trouble starting.

Why does the mass air flow sensor fail? One of the reasons for the failure of this device is incorrect installation of the air filter during its scheduled replacement. Like many consumables, the air sensor needs to be replaced regularly. It is important to change the air filter in a timely manner.

A sensor malfunction has little effect on engine performance. You can drive for some time with a faulty sensor. But this will lead to increased fuel consumption. The cost of a new sensor for Kalina is not very high, and you can do the replacement yourself. If necessary, the sensor can be replaced in service, during a routine inspection.

Causes of malfunction

"Check Engine" - translated from English means "Check the engine." It is this system that many car owners are beginning to check. The problem may be in one of the eight or 16 clogged valves of the Lada Kalina engine, injectors or electronic control unit.

Let's look at the problems that can cause the ECU to light up the check engine light on the Kalina instrument panel in more detail.

Spark plug

The first thing you need to check is the spark plugs of the Lada Kalina. It is advisable to carry out testing on a special spark plug stand. If it is not there, then the check can be done in the old-fashioned way.

There are two old-fashioned methods for checking spark plugs on a Lada Kalina. The first is to do the following:

1. Start the Kalina engine and remember how the engine works.
2. Disconnect the wires one at a time going to the breaker-distributor.
3. Listen to the motor running after each wire removal. If it remains the same on some spark plug, then this particular device needs to be removed and cleaned or replaced.

There is a second way to check, if the Kalina car owner is absolutely sure that the check light is on on the Lada due to the spark plugs.

1. Start the Kalina engine and remove the spark plug.
2. Bring it to the cylinder block.

Attention! Now don't be scared. The spark will be unexpectedly large if the element is alive. If Kalina’s candle is not working, then nothing will happen.

Experienced mechanics recommend checking the spark plugs of the Kalina engine on a special stand using a gun. The reliability of old-fashioned methods is not always correct.

Broken fuel tank seal, catalytic converter failure

1. If the seal of the fuel system is broken, air begins to flow into it.
2. Additional fuel consumption appears.
3. Air in the fuel system causes engine problems.
4. The check engine light comes on on the dashboard.
