P1426 fault cause error

December 29, 2014 Lada.Online 662 394 78

In the event of malfunctions in the operation of the vehicle, the engine electronic control unit (ECU) stores errors in memory. In the future, Kalina ECU errors can be read using an on-board computer or special equipment for car diagnostics. In addition to controller error codes, it is possible to perform Kalina self-diagnosis on the dashboard.

Advice

: To read errors in electronic units, car owners often use the ELM327 adapter (buy on Ali) and the OpenDiag application in their smartphone.

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:

Turn off the ignition.
Press and hold the daily mileage reset button.
While holding the button, turn the key in the ignition.
Having done this, all sensor indicators on the dashboard will light up, and the arrows of the tachometer, speedometer, antifreeze temperature sensor and gasoline level in the fuel tank will move on a scale from zero to maximum. Next, press the button located on the steering column wiper switch. This way you can switch the data on the instrument panel screen. On the first one you can see the process of checking the functionality of the instrument panel. The second will show the version of the software installed in the car, and the third will show combinations of faults.

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.

Then press the button located on the steering column wiper switch. This is done in order to switch the data mode on the instrument panel screen.

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.

How to check errors on Niva

You will need to connect a special scanner to OBD2. The device reads all the codes and displays them on the display. If you don’t have access to such equipment, you can use the self-diagnosis mode. It's done like this.

Turn off the ignition.
Open the fuse box cover at the driver's left knee.
Find the diagnostic block and close the two outermost contacts of the top row.
Next you need to turn on the ignition.
After this, the check engine light will flicker on the instrument panel.
The number of indicator blinks will help you read the code.

DTC Engine or automatic transmission error P1141

On our resource you can ask questions and share your own experience in troubleshooting problems associated with error P1141. By asking a question within a few days you will be able to find the answer.

Taking into account the fact that OBD2 errors in the operation of the engine or other electronic systems of the car do not always directly indicate a non-functioning element, and the fact that for different brands and models of cars the same error can arise as a result of a malfunction of completely different elements of the electronic system, we have created this algorithm for assistance and exchange of useful information.

We hope, with your help, to form a cause-and-effect relationship for the occurrence of a particular OBD2 error in a specific car (make and model). As experience has shown, if we consider a specific make and model of a car, then in the vast majority of cases the cause of the error is the same.

If the error indicates incorrect parameters (high or low values) of any of the sensors or analyzers, then most likely this element is working, and the problem must be looked for, so to speak, “upstream”, in the elements whose operation is analyzed by the sensor or probe.

If the error indicates a constantly open or closed valve, then you need to approach the issue wisely, and not thoughtlessly change this element. There may be several reasons: the valve is clogged, the valve is jammed, the valve receives an incorrect signal from other faulty components.

Errors in the operation of the OBD2 engine and other vehicle systems (ELM327) do not always directly indicate a non-functioning element. The error itself is indirect evidence of a malfunction in the system, in a sense a hint, and only in rare cases a direct indication of a faulty element, sensor or part. Errors (error codes) received from a device or scanner require correct interpretation of the information, so as not to waste time and money on replacing working elements of the car. The problem often lies much deeper than it seems at first glance. This is due to the fact that information messages contain, as mentioned above, indirect information about the disruption of the system.

Here are a couple of general examples. If the error indicates incorrect parameters (high or low values) of any of the sensors or analyzers, then most likely this element is working, since it analyzes (produces certain parameters or values), and the problem must be looked for “upstream”, so to speak, in elements whose operation is analyzed by a sensor or probe.

Another point that I would like to note is the specifics of a particular brand and model. Therefore, if you recognize an error in the operation of the engine or other system of your car, do not rush to make hasty decisions, but approach the issue comprehensively.

Fixing breakdowns

After the diagnostic procedure, and determining why the VAZ Kalina 8 valves are capricious, it is necessary to completely check the entire line of the unit, which is indicated by the decoding of the index. This must be done by testing the main line and replacing the blocks with known good ones. Additionally, the specifics of operation should be taken into account - due to constant shaking on broken roads, the standard terminals can become loose, which provokes a breakdown in contact. In this case, the computer will also indicate the presence of a malfunction. In order to prevent this, experienced craftsmen recommend treating connectors with special impregnations that repel water and carry out preventive maintenance in a timely manner.

Diagnosing Lada Kalina errors requires the necessary equipment and knowledge of how to decipher the indices generated by the program. In the absence of proper experience, information can be misinterpreted, which will lead to unnecessary procedures and waste of time. If necessary, you can contact a qualified specialist, but the services of service station masters are not cheap.

Checking with a plug-in tester

More accurate and comprehensive diagnostics can be performed using a connected computer or a special tester. However, the data displayed on the screen is alphanumeric. The letters have the following meaning:

In addition, the number 0 means OBD code 2, numbers 1 and 2 indicate the enterprise code, and 3 is the backup password.

Basic ignition system

(the letter P precedes the digital designation):

Fuel-air system

(the letter P is located before the numbers):

In principle, diagnostics using BC makes it possible to identify the main faults. Basic error codes for Priora 8 and 16 valves using a plug-in tester provide significantly more information. To understand it, you should study the decoding of indicators, which is not so difficult.

Modern Lada model

Like any modern foreign car, the Lada Priora has many different sensors installed. The condition of important vehicle systems depends on their correct operation. The problem is that if some sensors fail, the Priora can continue to move. Faults of this kind can lead to increased fuel consumption, unstable engine operation, and increased wear of parts, but the car will drive, and you will only find out about the fault when it means you have to make expensive repairs.

In order not to go into the engine compartment with a multimeter, the Priora has a controller that allows you to check faults using a special tester, a plug-in or built-in on-board computer. In order to diagnose the systems, just press 2 buttons and look at the error codes.

Replacing the device

Technical properties of the sensor:

Checking the ADC pulse of the VAZ rough road sensor can be carried out using the DST-2M device or its analogues. The BSMW indicator is analyzed and diagnosed in the form of acceleration configuration g. If the sensor is subjected to a slight impact with a click or knock, then there is a change in acceleration values with a different spectrum, from instantaneous to small values. In principle, this device is very sensitive, changes are observed even by the body's rocking.

Error codes for VAZ rough road sensor:

To dismantle the Priora rough road sensor you will need a Phillips head screwdriver:

Replacement

Installing a new sensor is not a difficult job. To carry it out you will need a minimum of tools, as well as a little time:

Thus, work to replace the sensor is carried out on Lada Kalina and Lada Priora. On machines of other brands and models, this work may be performed differently.

Manufacturers

. If you have a foreign car, then it is better to purchase an original sensor from official suppliers. Even the most expensive models will cost relatively little. You shouldn’t save money and buy a Chinese “pig in a poke”; no one will guarantee the service life of the part.

Several of our companies produce DND for domestic production. The most famous are Kaluga sensors and those produced in Zelenograd. Connoisseurs of German quality can purchase a device manufactured by BOSCH.

Checking using a connected computer or tester

Driver Information Panel

Checking system malfunctions using connected devices gives more accurate results, but at the same time requires deciphering special codes. For example, the monitor displays code p0441 or p0130 or error p0422. Oh, these car manufacturers, in human language they could write “replace the oxygen sensor” instead of P0130 or “check the canister valve” instead of P0441. But nothing can be done, the Lada Priora is also intended for export, so it is easier to write p0441 in the program than to give explanations in Russian, Kazakh, Arabic, Armenian and 10 other languages. And then attach special tables that indicate the meaning of certain codes. Just look at them and everything will become clear. But these tables are not included with the operating instructions. Either way, you can check them out below.
