Reasons why the speedometer of a Lada Granta car does not work

Information about the current speed of movement on the on-board computer of the Lada "Grant" comes from an electronic sensor. The Lada Granta speed sensor is installed on the gearbox. Despite the simple design, this part is extremely important for the correct operation of the electronic engine control unit. Together with the other six sensors (temperature, phases, crankshaft position, air flow, detonation, oxygen content), it generates the data necessary for economical, safe and reliable engine operation.

What speed sensor is on Grant

As is already becoming clear, replacing the speed sensor on a Grant is not a complicated procedure that an ordinary car owner can handle. You just have to choose a part that fits this car model and will perform all the necessary functions.

The speed sensor on the Lada Granta is a fairly universal part, which is also used in other Lada models: LADA Priora, LADA Kalina.

In conclusion, it is worth adding that before installing the DSA on the car, it is necessary to wipe the seat area of ​​the part with a rag in order to prevent debris from getting inside the gearbox. The sensor itself is inserted all the way until it clicks, only after that the fastening nut is screwed back in.

So we found out where the speed sensor is installed on the Lada Granta, and how to change it. If you have questions, you can ask them in the discussion.

The speed sensor on the Grant is located on the gearbox. It works as follows: in the gearbox there is a special mark on the gear wheel, which, when this wheel rotates, generates an impulse using a speed sensor. It is by the frequency of these pulses that the speed of the Lada Granta is determined.

The DS on the Grant, like on many cars, is located quite low, so it is exposed to water and dirt. If we remember that the speed sensors themselves on domestic cars are not highly reliable, then it becomes clear why they fail so often.

• The speedometer needle does not react to speed in any way (it lies at zero);
• The speedometer readings change, but do not correspond to reality.

Due to the inconvenient location of the sensor itself, replacing it is quite difficult. First of all, you need to disconnect the pipe that goes from the air filter to the throttle. This will improve access to the sensor itself.

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 of the gearbox 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 displayed on the instrument panel.

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.

Where is the speed sensor on the Lada Granta: photo and price

Car: Lada Granta. Engine: 21116. Asked by: Damir.

Yesterday I came home, started climbing onto the curb and slightly hit the bottom of the car. And then it started. The speedometer needle began to dance, at first it seemed to me that it was even accompanied by music. Then it twitched at zero, twitched to 200, and fell again. No errors occurred; the engine warning light did not light up on the instrument panel.

She didn't get up again. I drove around the yard, looked smartly under the hood, and screwed in all the chips I saw. Did not help.

Knowledgeable people said that the speed sensor was broken, quite logical, but where is it located? I went to a car store to buy a new one to check, the store is good, they accept returns if there was no loss of presentation. And the seller told me that when the speed sensor breaks down, the electric power steering also doesn’t work, but for me it works.

Speed ​​sensor location

An expert on Lada cars with many years of experience. I own a Lada Granta car, I collect cramps based on the Priora. Sometimes I stay overnight in the garage. My wife is more jealous of cars than of women.

The speed sensor on the Lada Granta is located between the BDZ (throttle valve unit) and the brake fluid reservoir.

Replacing the speed sensor

1. The sensor can be removed by removing the air filter and inlet pipe.

Remove the pipe and move the air filter housing to the side

• The sensor is secured with a nut, which can be easily unscrewed with a regular 10 mm wrench.
• Unscrew the nut, disconnect the chip, and remove the speed sensor.

After you have removed the sensor, clean it; debris may have gotten on it. Since its body consists of a magnet, it could become clogged when it hits a curb.

New and old speed sensor

However, this is unlikely; most likely it has failed and requires replacement. But if there was dirt on it, then there is a chance that it is working. Put it back, connect the chip and test drive it to check.

Electric power steering failure due to speed sensor failure

Indeed, if the speed sensor breaks down, the electric power steering in some cars fails, and error P-0501 (Vehicle speed sensor signal outside the permissible range) should appear on the instrument panel. That's why the steering wheel refuses, so that the car understands that the sensor is broken. In your case, the nature of the failure said that the sensor shows zero speed.

Failure of the electric power steering may indicate a breakdown of the speed sensor!

Sensor price

A speed sensor costs from 300 to 600 rubles.

The speedometer needle of the VAZ-2109 twitches

The first thing car owners need to do if they notice that the speedometer or tachometer, and sometimes the electric power steering, will begin to work intermittently or stop functioning altogether is to check the car's electrical system for serviceability. The check is done in the following sequence:

• the battery is disconnected from power for 5-7 minutes;
• disconnecting from the power will allow you to reset all settings of the on-board computer;
• If after connecting the wires to the battery the fault cannot be eliminated, the cause of the breakdown must be sought in one of the elements that is used in the operation of the speedometer.

When resetting the chip does not help to cope with the speedometer malfunction, you should conduct a full check of the power circuit. To do this you will need:

1. Check the fuse plate installed on the fuse board in the speedometer power supply circuit. The required fuse is designated "IG/METER";
2. Next, the serviceability of the wiring in the area from the speed registration sensor to the instrument panel is diagnosed. Often in this section the wires are torn, pinched and get other defects, largely due to the constant shaking of the car while driving on not the best roads;
3. Also, when checking the wiring, it is necessary to inspect the contacts in the connectors, which may become unusable due to oxidation and rust formation. It would be a good idea to clean the sensor contacts and connectors;
4. The next step is to check the vehicle distance control sensor. Service centers use diagnostic equipment to check it. If there are no diagnostic tools, you can check the operation of the sensor by driving a few kilometers. When the mileage count continues, this indicates that the sensor is working.

Often, fixing the problem will require removing the dashboard. This takes a lot of time, although almost anyone can cope with this task. To dismantle, you need to remove the radio and cigarette lighter, the emergency lamp and unscrew all the necessary fasteners. Now you can begin the actual repair.

If the speedometer needle twitches when accelerating, then most likely the problem is in the drive, which has failed. Therefore, you need to remove the drive, gears, and seals. The latter must be replaced with new ones. Next, it is advisable to troubleshoot the gears. If the edges on them are licked off, then we change them.

In addition, it is advisable to check the cable. It is likely that it hits something while driving, which causes the speedometer needle to jump. If necessary, replace the cable and lubricate it. Next we carry out the assembly.

Parts and consumables:

The speed sensor on the Lada Granta is located and installed on the gearbox. When the drive wheels rotate, the speed sensor generates 6 pulses per 1 m of vehicle movement, and the controller determines the vehicle speed based on the pulse frequency.

1. Disconnect the wire from the negative terminal of the battery on the car.

2. Disconnect the wiring harness connector from the speed sensor by prying the plastic latch.

3. Using a 10 mm socket, unscrew the sensor mounting nut.

4. Remove the speed sensor from the gearbox housing by prying up its housing with a screwdriver.

5. Replace the faulty speed sensor with a new one.

6. Install the speed sensor in the reverse order of removal.

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: Knock in the suspension of Lada Grants - repair at an official dealer

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.

While driving a Lada Granta, we often look at the speedometer readings to see how fast we are going. It depends on this whether we violate traffic rules or not, but if the speedometer shows deviations or no readings at all, then you can get a good fine. The speed sensor (DS or DSA) is responsible for transmitting the correct speedometer readings. A sensor malfunction is detected by the following symptoms: while driving, the speedometer needle is at zero or the readings are incorrect. The Lada Granta sensor itself is a durable part and rarely fails, but it all depends on the manufacturer. Many people don't even know where it is installed. If this is related to speed, then the increase or decrease in speed is regulated by the gearbox, then the DS is installed in the gearbox.

Malfunction in the instrument cluster

Often the speedometer stops working due to a malfunction of the instrument panel itself. The easiest way to check this is to temporarily connect a known working panel. It is also worth checking the reliability of the contacts on the back of the dashboard. You can also check the vehicle speed readings on the on-board computer.

If the dashboard was tuned (disassembled), then the arrow motor may have been damaged during the work, or the speed arrow is set too deep (the arrow touches the panel trim).

Replacing the Lada Granta speed sensor

Removing the speed sensor on a Lada Granta car is done to replace it with a serviceable one in case of failure. The sensor is installed on the gearbox.

The principle of operation is to generate an electrical impulse when the drive wheels rotate. Six pulses correspond to one meter of vehicle movement. The controller determines the current speed of movement based on the frequency of pulses from the sensor.

To replace the speed sensor you will need a ten key. You should also turn off the power to the car by disconnecting the minus terminal from the battery. Do the following sequence of actions:

• Lifting the plastic latch, disconnect the connector with electrical wires from the sensor.

• Unscrew the sensor mounting nut and remove it from the gearbox housing.
• Replace it, then install in the reverse order.

At this point, the repair work to replace the speed sensor on the Lada Granta car has been completed.

Where is the speed sensor on the Lada Granta and how to change it

Perhaps not every car owner or Grant holder can answer the question: where is the Grant speed sensor located? This is explained by several reasons.

First of all, the Lada Granta speed is a fairly high-quality and durable part that fails quite rarely. Also, the product itself is small in size and it will be quite problematic for a non-professional to see it from under the hood right away. Therefore, let’s find out after all, where is the Lada Granta speed sensor located?

Causes and their elimination

Why doesn't the speedometer work? The reasons may be the following:

1. Rope break
2. Malfunction of the sensor itself

Before you start troubleshooting, you need to prepare the necessary tools:

• Standard home tool kit
• Silicone (as a sealant)
• Plastic fork.

Before you start, think about safety and check whether the car will move on its own.

Then you need to disconnect the battery from the car (just remove the contact from the negative terminal).

To repair the speed sensor, there is no way to do it without completely removing the dashboard. And to remove the dashboard, you need to dismantle all existing linings, jumpers and remove the steering wheel and functional switches near it. Next, when the torpedo is free and nothing prevents it from being removed, do this by first unscrewing all the fastening bolts.

All contacts and wires from the dashboard must be disconnected and marked so that there are no questions when connecting back. Now you can disconnect the broken sensor from the torpedo; to do this, you may also have to unscrew a few mounting bolts. There may be some problems at the time of detachment but, as a rule, it is necessary to slightly heat the connection and both parts will separate.

After this, take a meticulous look at the cable. There should be no obvious mechanical damage on its surface. If you notice any damage to the cable (dents, breaks), then this may well be the reason why the speedometer does not work.

If the cable is in normal (good) condition, then you need to check the arrow axis. Sometimes it happens that the axis bends, thus preventing its free movement. This is where a prepared plastic fork comes in handy.

In the vast majority of cases, injection VAZ-2110s are equipped with electronic speedometers. And, as a rule, they are often alarmed by malfunctions that can manifest themselves in different ways. And if a car owner encounters a problem when the speedometer on a VAZ 2110 does not work, he needs to find out the degree of complexity of the breakdown. After all, the device may not work at all or work, but partially and with visible malfunctions.

To eliminate the problem, you need to identify the causes of its occurrence.

Typical causes of speedometer failure

It’s no secret that on the VAZ 2110 the speedometer plays a significant role in its operation. If you take a wiring diagram from a car, you will notice that the electronics are powered by a mounting block with a 10 amp fuse.

When the speedometer breaks down, the first thing you need to do is check all the contacts.

. Perhaps the malfunction occurred due to oxidation of one of the contacts.

If the contacts are in normal condition, it is worth thinking about possible problems in the speed sensor

. Or rather, in its connectors. The fact is that they are located in such a way that they are constantly in contact with dust, dirt and moisture. Therefore, it would be a good idea to tug the wires a little to shake off any possible contamination. It’s better to try to get them out and clean them more thoroughly.

Where is the speed sensor on the Lada Granta?

So where is the Lada Granta speed sensor located? It is reasonable that the part associated with the transmission of data on the vehicle’s speed, idle speed, and fuel consumption modes is located somewhere nearby or, specifically, on the vehicle’s gearbox housing.

But, in order to see this unit with your own eyes on Grant’s car, by opening the hood, you need to perform the following preliminary function: the inlet air supply pipe from the throttle assembly is turned out and dismantled.

This way, you can see where the speed sensor is located on the Grant. Now, at the bottom of the gearbox housing, you can see a part with a suitable plug and wiring. The next method to get acquainted with where the speed sensor is located on the Grant is to watch the video: where is the Lada Granta .

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.
