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
- 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.
Nut 10 and the chip is removed
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 abs light came on, what should I do?
ABS is the first and most common active vehicle safety system. In Europe, mandatory ABS equipment for manufactured models is legally established, so it is not surprising that even cars belonging to the budget category are equipped with it. But in such cars it is almost the only one; in versions of the middle and premium categories, the number of such systems is large, and many of the additional systems are built on ABC.
The anti-lock braking system prevents the wheels from completely locking when braking, which increases the effectiveness of the brakes and maintains the controllability of the car by preventing it from skidding. ABS is useful, but at the same time, it is another component of the car, which includes a number of structural elements and components. And the more complex the machine and the more additional parts it contains, the less reliable it is.
System Features
ABS consists of two parts - electronic and mechanical. The “weak” link in it is the electronics. It is sensitive, so even the slightest negative influences lead to interruptions in operation.
In a car equipped with ABS, there is a warning mechanism that signals the cessation of operation. And he does this by means of a warning light on the dashboard.
When the ignition is turned on, this lamp lights up as self-diagnosis occurs. The system checks its performance, and if no violations are noticed, the lamp goes out, indicating that the ABS is in working condition.
But drivers are faced with the fact that the ABS warning light comes on while driving, and this can only happen under certain conditions. For some, the signal may not go out at all, for others the lamp lights up only when a certain speed is reached. The warning light that comes on confuses the owners, and the reason for this is simple - ABS works with the brakes and they perceive a malfunction of the system as problems with the braking system, which is wrong.
ABS is an addition to a car's braking system that increases its efficiency. Therefore, even if the ABS malfunctions, the car remains able to brake, but you need to get used to the operation of the brakes.
The anti-lock braking system is designed in such a way that if a malfunction is detected, it immediately turns off completely so as not to have any effect on the operation of the brakes.
Car enthusiasts solve an ABS problem by removing the fuse responsible for the operation of the system and postponing troubleshooting until a suitable occasion. But this will not work if the car is equipped with a number of security systems and some of them are based on ABS. In this case, it will not be possible to continue driving, since the electronics will block the operation of a number of components and systems due to a malfunction. It is better not to delay eliminating the cause of the anti-lock braking system malfunction.
: The ABS light is on on the instrument panel. The brake lights do not go off.
As already noted, breakdowns occur in the electronic component, which includes sensors installed on the wheel hubs and the control unit. The mechanical component does not cause problems.
The “culprits” for the ABS warning light coming on:
- fuse;
- wheel speed detection sensors;
- setting elements of sensors;
- wiring;
- Control block.
Why the ABS fails can be easily identified by checking the listed components if the car is equipped with an on-board computer with a display on which error codes are displayed. This will significantly narrow down your search, since you can find out from the code which sensor is acting up.
In a car without an on-board computer display, to determine the malfunction, you will have to look for a scanner and connect it to the diagnostic connector to determine what caused the failure.
Note that identifying the error code will make the search easier, since diagnostics will not provide accurate information; it will indicate where to look for the fault. Therefore, you can even do without scanning.
Looking for a reason
You should start troubleshooting with the fuse. If this element burns out, the ABS does not work. Note that you should not always go into the fuse box, since the behavior of the system itself can give a “hint” regarding the serviceability of the fuse. For example, if the ABS light on the instrument panel comes on only under certain conditions, but after turning off the power to the ignition switch and restarting the engine, the problem disappears, then the problem is clearly not in the fuse. It should only be checked if the warning light is constantly on.
The sensors are located in a place that cannot be called well protected. Therefore, dirt sticking to it will easily cause a malfunction, causing the system to shut down.
Sensors may simply break during the process of repairing and servicing the chassis. Careless work and the use of impact tools during disassembly often cause internal damage to the sensors. Since they cannot be repaired, the damaged element will have to be replaced to restore ABS functionality.

Replacing the speed sensor on a Lada Granta car
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.
The speed sensor is important for driving safety
On Priora, the reliability of the speed sensor is rated as average. Possible disadvantages:
If there is a problem with the speed sensor, the controller enters data with code “24” into RAM and lights a signal indicating the need to check the engine. If the car has problems with the engine idling, but the “Check Engine” signal does not come on, then the problem may be with another sensor (mass air flow).
Checking the operation of the speed sensor begins with grounding on the third contact and supply voltage (12 V) on contact “1”. Pulse signals on the second contact are carried out at a speed of at least five kilometers per hour for the drive wheels.
To study the state of the second contact, an oscilloscope or multimeter is usually used; for the first and third contacts, you can use the dialing technique.

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.
You need to lift the hood, unscrew the pipe that goes to the throttle valve, and move it to the side. Below you can see where the sensor is installed on the gearbox housing. We remove the wiring block from the sensor, unscrew the mount and pull out the DS from the gearbox housing.
It is necessary to check the integrity of the wires that go to the sensor, whether there is oxidation of the contacts, this must be eliminated. When you remove the sensor, pay attention to the presence of mechanical impurities on the sensor.
The presence of impurities indicates that the gearbox lubricant needs to be replaced and also affects the transmission of correct readings. When buying a sensor, you need to have the same markings as the one you had, because not all sensors are suitable.
Before installation, you need to clean the place where the sensor is inserted and lubricate the rubber ring on the sensor with oil. We insert the sensor into place until it stops and secure it with a nut. This description is made for the Lada Grant, which does not have ABS.
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?
What speed sensor is on the Grant?
Perhaps not every car enthusiast or owner of a Lada Granta car can answer the question: where is the Granta speed sensor located? This is explained by several reasons.
First of all, the Lada Granta speed sensor is a fairly high-quality and durable part that rarely fails. Also, the product itself is small in size and it will be quite problematic for a non-professional to immediately notice it from under the hood. Therefore, let's still find out where the Lada Granta speed sensor is located?
Where is the speed sensor on the Lada Granta?
So where is the Lada Granta speed sensor located? It is logical that the part associated with the transmission of data on the vehicle’s speed, idling, and fuel consumption modes is located somewhere near or directly on the vehicle’s gearbox housing.
However, in order to personally see this unit on Grant’s car by opening the hood, it is necessary to perform the following preparatory procedure: the inlet air supply pipe from the air filter to the throttle assembly is unscrewed 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. Another way to get acquainted with where the speed sensor is located on the Grant is to watch the video: where is the speed sensor on the Lada Granta.
The speedometer does not work on the grant: the reason
If the speed sensor is faulty, the speedometer will show a zero value, and a check will appear on the instrument panel, indicating a problem that is easily identified if you know the error code. Removing the speed sensor is much easier to do using an inspection hole, because it is much easier to reach it from below than by opening the hood. After the speed sensor has been replaced, the error data must be cleared from the ECM. This is very easy to do if you remove the battery terminal for a few minutes.
If the speedometer needle twitches, and after that it occasionally stops working and starts again, it can be assumed that sometimes contact is lost in the pads. If this malfunction remains without due attention from the driver, then after a certain period of time the contact will be completely destroyed due to corrosion, and the sensor will stop sending signals to the ECM, and the operation of the device will cease. Therefore, when installing the speed sensor again, you need to seal it so that it and the contacts are completely protected from moisture.
The electrical circuit of the speed sensor is protected by fuse F7. It also sometimes burns out during short circuits, but when this happens, not just one speedometer, but the entire engine of the car stops working. This can be explained by the fact that this fuse not only protects the speed sensor, but also acts as a protector for the MAF (mass air flow) sensor and the oxygen sensor.
Now if you notice that your speedometer on the grant does not work, the reason will be immediately clear to you.

The speed sensor, which is located in the gearbox housing, is responsible for the normal operation of the Lada Granta speedometer. It is located in a rather hard-to-reach place and replacing it is not easy unless you remove anything. But it is best to first disconnect the thick pipe that goes from the air filter to the throttle. After this, practically nothing will interfere with us.
To perform this repair you need a minimum of tools, but still I will give a list of what is needed below:
- screwdrivers - preferably both flat and figured
- wrench 10 - the ideal option would be a head with a ratchet, since it is very difficult to get to with a regular wrench
First of all, disconnect the power plug from the speed sensor. It is secured using a plastic clip, which must be bent slightly and the block pulled up to remove it.
Then use a head to unscrew the sensor mounting bolt: Now we pry up the speed sensor housing, as it fits a little tight. It is most convenient to use a flat screwdriver and the thinner it is, the better:
Now you can remove it from the hole in the gearbox without much effort. This is what it looks like after removal:
Installation is carried out in the reverse order of removal. As you can see, everything is extremely simple, but in terms of time it’s not so fast.
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.
Attention! If your Lada Granta is equipped with an ABS system, then the speed is read from the ABS sensors. In this case, the speed sensor at the gearbox is not connected and acts as a plug.
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.
Signs of a malfunctioning speed sensor:
- 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.
Replacing the speed sensor on Grant
In this case, if the speed sensor on the Grant fails, it will need to be replaced with a new one.
However, before purchasing a new part, you should reliably make sure that this is the problem. To do this, you need to check the condition of the corresponding car unit. We get to the place where the Lada Granta speed sensor is installed and perform the following checks:
• monitoring the integrity of the electrical circuit supplying the DSA. To do this, disconnect the power, carefully inspect the contacts for oxidation, tightness, contamination, and integrity of the insulation. If deficiencies are identified, they must be eliminated;
• monitoring the resistance of the sensor supply circuit (the value should be about 1 Ohm); • checking the condition of the speed sensor itself.
The speed sensor on the Grant itself changes in the following sequence:
• the sensor power plug is disconnected, the plastic clamp is bent and the part is removed; • the DSA fastening bolt is unscrewed; • pry up the housing and remove the sensor. The new product is installed in the reverse order.
Possible device malfunctions: signs and causes
One of the reasons for speedometer and odometer malfunction is a broken cable. This can be detected by the characteristic sound that is heard in the area of the shield. After a break, the steel ends of the cable touch the sheath, and noise appears.
If the pointer is faulty, the needle either shows incorrect readings or it lies down and does not rise. The cause may be the speed sensor. If it is broken, you need to replace it.
If the speedometer on a Priora does not work, first of all you should check the fuses, they could have blown. In addition, you need to test the wiring and make sure the quality of the contact connections. If the device does not work, it must be replaced.
How to check the device for functionality?
Before changing or repairing the speedometer, you should find the reason why it is not working. First you need to diagnose the speed sensor, since it is most often the cause of the pointer not working.
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.
How to identify a faulty ds?
The speed sensor is based on the following simple principle:
- The gear wheel of the transmission unit has a special mark that generates impulses through the DS during the rotational movement of the wheel.
- The speed of movement of the Lada Granta car is currently recorded by the frequency of the read pulses.
- As the speed increases, the pulse frequency increases.
- 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.
