Lada Granta speedometer does not work: reasons, repair

The domestic car Lada Granta (in Russian Lada Granta) is equipped with a power unit with fuel injection. This configuration requires clear interaction of all sensors.

One of the most important controllers of the electronic system of this car is the speedometer. The article will answer the question - why the speedometer does not work on the Lada Granta. The principle of operation of the entire speed calculation system, symptoms of malfunction and causes of breakdowns will be considered.

Basic faults

The Lada Kalina speed sensor can easily fail. Every car enthusiast can notice the problem. The main “symptoms” indicating the development of the problem are identified, including:

• lack of movement of the arrow (it just lies there);
• the pointer makes sharp jumps;
• the arrow freezes at speed even in the absence of movement;
• The electric power steering fault icon is on.

If the speedometer does not work, the most common reason for this phenomenon is a malfunction of the speed sensor. It is located on the gearbox, secured with one screw. There are three main wires connected to it. If it is a Lada Kalina with a 16-valve engine, you can find the device on the washer side. In the version with 8 valves, it is necessary to remove the bellows of the engine air filter.

To determine the device number, simply remove it and rewrite the numbers. There is no need to rush into buying a new part; first you need to check all contacts. In some cases, the malfunction is due to oxidation of the wires or damage to the wiring. Perhaps the problem is hidden in the presence of metal shavings or other particles.

Many experts have noticed that the malfunction of the speed sensor on Kalina is associated with problems with the electric power steering. If, after replacing the element, it still does not work, the device may be defective or unsuitable for the vehicle. Therefore, it is necessary to select it according to the assigned number.

Repair

For convenience, the device is dismantled before repair. Further repair actions will depend on the cause of the malfunction. In some situations, the actuator or O-ring will need to be replaced.

Sometimes, if the speedometer has stopped working, it is enough to remove it, inspect it, clean it, dry it for some time and treat it with sealant around the perimeter. In most cases, repairs will require replacing the speed sensor.

How to determine that the ds is faulty

The principle of operation of the speed sensor is as follows: there is a certain mark on the gear wheel that generates an impulse using the DS when the wheel rotates. The speed of the vehicle is determined based on the frequency of the received pulses. As the frequency increases, the speed of the machine increases. The signal from the speed sensor, as well as from many others, is output to.

The fact that the DS on the Lada Granta is located low indicates that it is strongly exposed to water, sand and dirt. This is the main reason for its failure. The following symptoms indicate that the sensor responsible for the speed of the Lada Granta car is faulty:

• the speedometer needle is at zero while driving or does not always work;
• unstable idling;
• The speedometer readings do not correspond to reality;
• fuel consumption increases;
• engine thrust decreases.

Please note that unstable engine idle speed and an increase may also be due to a malfunction of the Lada Granta oxygen sensor, which consists of two devices: a control catenary collector located in the upper part, and a diagnostic one installed in the catenary collector behind the converter.

Types of speedometers

There are currently three types of speedometers:

• mechanical;
• electrical;
• electromechanical.

On a mechanical type device, speed is transmitted from the gearbox using a cable. The distance traveled on the odometer is set by measuring the revolutions. Each revolution corresponds to a certain amount of mileage. The mileage traveled is reflected on the dial.

Mechanical device dial

In the electromechanical version, improvements have been made that eliminate the shortcomings of the mechanical device. The mechanical flaw was the cable, due to which the information was often incorrect. The electromechanical device is supplemented with a speed sensor, the signals from which are transmitted to the electric motor that rotates the gearbox.

All modern cars are equipped with an electronic device. The electronic speedometer measures the number of revolutions of the wheel. The mileage traveled is calculated by analyzing the wheel circumference and the number of revolutions. The information is reflected on the display.

Somewhere the contact is lost.

Check the contact in the connector on the box (on the speed sensor).

Or the sensor is covered. But the check should light up.

Checking the speed sensor

First you need to find out whether there is grounding and 12 V voltage in the contacts. These contacts are wired, and the contact with pulse signals is tested by torsion.

Method 1 (check with a voltmeter)

1. We remove the speed sensor.
2. We use a voltmeter. Let's find out which terminal is responsible for what. We connect the incoming contact of the voltmeter to the terminal that outputs pulse signals. We ground the second contact of the voltmeter to the engine or machine body.
3. By rotating the speed sensor, we determine whether there are signals in the operating cycle and measure the output voltage of the sensor. To do this, you can put a piece of tube on the sensor axis (twist at a speed of 3-5 km/h). The faster you rotate the sensor, the higher the voltage and frequency in the voltmeter should be.

Method 2 (without removing from the car)

1. Place the car on a jack so that one wheel does not touch the ground.
2. We connect the contacts of the sensor with a voltmeter.
3. We rotate the wheel and diagnose whether voltage appears - if there is voltage and frequency in Hz, then the speed sensor is working.

Method 3 (check with a control or light bulb)

1. Disconnect the pulse wire from the sensor.
2. Using the control, we look for “+” and “–” (after turning on the ignition).
3. We hang one wheel as in the previous method.
4. We connect the control wire to the “Signal” wire and rotate the wheel with our hands. If “-” lights up on the control panel, then the speed sensor is working.

Checking the DS with a tester

How to identify a faulty ds?

The speed sensor is based on the following simple principle:

1. The gear wheel of the transmission unit has a special mark that generates impulses through the DS during the rotational movement of the wheel.
2. The speed of movement of the Lada Granta car is currently recorded by the frequency of the read pulses.
3. As the speed increases, the pulse frequency increases.
4. The information is supplied directly by the speed sensor, like from some others, and is displayed on the dashboard.

Due to the unfortunate location of the sensor in question, where is it located? Low and close to the road surface, it becomes subject to dirt and moisture. This causes it to malfunction.

If an element fails, the following factors may indicate this:

• the arrow on the speedometer is located at zero or the device operates periodically;
• the engine runs intermittently at idle;
• the readings on the speedometer do not correspond to the actual speed;
• fuel consumption increases;
• engine thrust decreases.

Here you should pay more attention to the correct identification of this malfunction, since similar symptoms (unstable engine operation during idle and increased fuel consumption) may be present with a faulty LADA Granta oxygen sensor.

Let us remind you that the Lada Grant has two lambda probes. One is the control one (in front of the catalyst), the second is the diagnostic one (behind the converter).

The functions of the first include monitoring and adjusting the composition of the air-fuel mixture, and the second is necessary to register the presence of oxygen in the exhaust gas.

Possible breakdowns

Troubleshooting in the speed calculation system must be looked for in the electrical circuit. It is better to start work with the fuse.

Fuse

A 10 A fuse is responsible for protecting the instrument panel. It is located in the fuse block and is marked “F1”. It is necessary to remove the element and visually inspect for a break in the internal jumper. If there is no break, but there is melting of the case, then the protection device must be replaced with an exact analogue of 10 amperes. Additionally, you need to inspect the fuse contacts, eliminate any defects, and clean them.

After installing a new fuse, you need to check the circuit for electric current. To do this you need:

1. Turn on the ignition.
2. Set the multimeter to DC voltage measurement mode.
3. Connect the red test probe to the fuse output.
4. Black dipstick with ground.

The tester should show a voltage similar to the battery charge. It is prohibited to connect the power circuit directly without a protective device, through twisting, or to insert foreign metal objects between the contacts, as this may lead to a fire.

Sensor

If after replacing the fuse and checking the circuit, the problem with the speedometer does not go away, you need to check the speed sensor. This requires:

1. Loosen the clamps securing the air purification filter pipe and remove it.
2. Disconnect the EMF power plug.

Both halves of the connecting plug must be checked for dirt, oxidation, and broken contacts. Next, the voltage supply to this plug is checked. Necessary:

1. Connect the red measuring probe to terminal “1”.
2. Black probe to terminal “3”.
3. Turn on the tester in DC voltage measurement mode.
4. Start the power unit.

The tester should give a result of 12 volts. Such data will indicate the supply of voltage to the sensor terminals. If there is no voltage, then you need to determine the damage by inspecting the wires for a break. Any damage should be repaired by replacing the faulty wire.

How to tighten the electric power steering rack?

The appearance of a knocking sound in the operation of the electric power steering is associated with the need to tighten the steering rack.

New Lada: Engine problems (troits, jerks, pulls poorly), causes

How to do it right:

1. First you need to disconnect the battery; to do this, disconnect the terminals from it. Unscrew the battery mount; to do this, you need to unscrew two more nuts located at the edges. After this, the battery is removed and put aside.
2. Then you need to lift the plastic stand, there are four more screws under it, they can also be unscrewed.
3. Having done this, it is necessary to move this stand forward until the platform is disconnected from the air filter housing retainer pad. After this, the trim can be moved back, this will provide freer access to the rail itself.
4. At the next stage, you will need to crawl your hand under the rail. Directly below it, as shown in the photo, there is a rubberized cap; it will need to be removed, this will allow the key to access the adjusting nut.
5. To perform adjustment work, you will need a special wrench to tighten the rack; without it, the adjustment procedure will not be possible. Using this wrench, you need to crawl under the car rail to install the tool in the required hole.
6. When adjusting, be careful not to overtighten the rack. If its tightening is very strong, then when cornering the rack will bite, and this, in turn, may affect the safety of movement. The angle of adjustment is always different, it depends on how much the nut is loose, but usually when performing such work the nut is tightened by approximately 30 degrees. This should be enough to get everything right. After the adjustment is completed, it will be necessary to check that this task was performed correctly. That is, you will need to make sure that the steering wheel turns normally to any position all the way and there is no knocking. If the knock remains, then the adjustment continues.

Replacement

It is necessary to remove the speed sensor very carefully. You will see that there is a thick pipe going from the air filter to the throttle body. It needs to be disconnected to improve access. After the pipe is disconnected, the speedometer is removed.

1. Disconnect the power plug from the speed sensor.
2. Using a wrench, unscrew the screw securing the gearbox sensor.
3. Using a screwdriver, pry up the resulting hole and remove the device.
4. Inspect the seat and the removed wire. If contamination is found, clean it.
5. Also inspect the gearbox. If oil stains are found, replace the O-ring.
6. The new or repaired device is installed in place.
7. Assemble the drive.

The design of the speedometer is based on electronics. But, nevertheless, almost anyone can fix its breakdowns.

If you doubt the result of the repair, or you were unable to complete it, it is better to seek help or advice from a professional auto mechanic. If the car's warranty has not yet expired, you should not start repairing it yourself, even if you are confident in your abilities.

A speedometer malfunction is a very serious failure and should not be allowed to occur under any circumstances. A timely solution to the problem will prevent disruptions to the operation of other vehicle mechanisms.

Removing and installing the electronic power steering control unit on the Lada Kalina

For this repair you will need a Phillips screwdriver, the whole job will take at least half an hour, as you will have to. After you have “got rid of it”, you can move on.

• First, unscrew the three bolts securing the plastic trim below the panel:

• After it is removed, the control unit becomes accessible, as shown in the photo below:

• The next step is to disconnect all the plugs and wires, out of three. They are attached as usual using latches and are very easy to remove.

• Now you can unscrew the two mounting bolts with a Phillips screwdriver, which are shown in the photo below:

• After this, we take it by the upper part and lower the electric power steering control unit down, since it is still attached to the plate. It lowers simply, just apply a little effort and it will be almost at the very pedals, it is clearly shown below:

• And there is very little left to do - unscrew the three bolts securing the power steering unit from the plate on which it is installed:

• And holding it from below, we take it out freely. For reference, my 2022 Kalina has a used unit made in Korea. And thank God it’s not ours, the quality of the Korean assembly will be better than that of our craftsmen. At least, I never had any problems with the electric booster in 2.5 years of use.

A couple of weeks ago strange glitches in the behavior of the car began. At times the speedometer stops working. At the same time, the electric power steering works at full power, the steering wheel becomes very light and not at all informative. Miracles also begin with the gas pedal, the acceleration when pressed is too sharp, the movement is jerky. After some short time, everything goes away on its own, the speedometer needle shows the speed, the steering wheel becomes heavier, the gas pedal behaves adequately. The STATE does not see any errors in this. As far as I managed to understand, when the speed sensor dies, the speedometer turns off and the power steering does not work at all. For me it’s the other way around. What else could be the reason for this strange behavior? The car is under warranty, but there is no point in going to the dealer, since the malfunction is not permanent, but rarely appears, but is quite unpleasant. Yes, most likely there is a speed sensor. It doesn't cost much money. DmDmT View profile Find more posts by DmDmT. Where is the speed sensor located? I have the same problem.

Principle of operation

DS of this type is located in all VAZ cars, and the 8-valve Granta engine is no exception. The basis of the work is the Hall effect. Each of the 3 contacts located on the sensor performs its own function: pulse - is responsible for generating pulses, grounding - turns off the voltage in case of leakage, power supply contact - ensures current transmission.

The operating principle is quite simple:

• A special mark, which is located on the gear wheel, generates impulses when the car wheels move. This is facilitated by the pulse contact of the sensor. One revolution is equal to recording 6 pulses.
• The speed of movement directly depends on the number of pulses generated.
• The pulse frequency is recorded and the resulting data is transmitted to the speedometer.

Increasing the speed increases the pulse frequency and vice versa.

Common defects and how to fix them

There are three main reasons that negatively affect the stability of the speedometer: oxidation of the connector wires, damage to the mechanical part, and cable failure. Next, we will look at how to identify these breakdowns and what actions are best to take to fix them.

Damaged cable

Oxidation of connector cores. During vehicle operation, the sensor connector wires may become oxidized due to water or any other liquid getting on them. This can be easily identified by visual inspection of the wire. If traces of corrosion or oxidation are found on the wire, they are cleaned, after which the operation of the speedometer is checked.

Damage to the mechanical part of the device. Failure of the mechanical part of the speedometer is also quite common. You can make sure that it is a malfunction of the mechanism that is causing the breakdown only after removing the speedometer. The dismantling process directly depends on the make of the car. As an example, we will look at recommendations for removing the speedometer from VAZ cars. If your vehicle is equipped with a new type of speed sensor, you will need to remove the dashboard to remove it. This is done as follows.

There is probably not a single modern car left whose speedometer needle is driven mechanically - by a gearbox and a cable. Today, almost all speedometers and odometers are digital. In a Chevrolet Lacetti with an automatic transmission, the speedometer and odometer receive information from the automatic transmission control unit, which in turn works in tandem with the MR140 or HV240 electronic control unit. But today we will talk about malfunctions of the Chevrolet Lacetti speedometer with a manual transmission.

Speed ​​identifier in vehicle design

Repairing any kind or replacing a speed sensor is a simple procedure, but it requires a clear understanding of its structure in the car’s design. Without knowing such information, answer questions like:

• How to check sensor
  for proper operation?
• Where is sensor
  ?
• How to remove the speed sensor?
• What is the connection diagram for the speed sensor?
• How to replace the speed sensor?

To begin with, let us repeat that the location of the speed sensor on almost all cars involves its installation in the speedometer drive (often called the sensor drive). Often, to find the speed ID, it is enough to find the wire coming from one of the front wheels and follow it to the place where it is next connected. The device he approached is a speed sensor, which is often located at the gearbox. The part almost always looks similar to the images below:
