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?
Speed sensor repair on Lada Grant
To record the exact speed of movement, use the Lada Granta speed sensor (abbreviated as DS or DSA). It is located at the gearbox.
Despite its small size, it is one of the main devices of the vehicle. The Lada Granta engine management system is equipped with 7 main sensors: engine temperature sensor, oxygen sensor, speed sensor, as well as crankshaft position, phase, detonation and mass air flow sensors. The reliability and safety of the vehicle unit directly depend on the condition of these devices.
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.
Please note that unstable engine idling and increased fuel consumption can 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. They operate on the same principle and are interchangeable. The control oxygen sensor monitors the adjustment of the composition of the air mixture supplied to the injectors. The diagnostic oxygen sensor signals the presence of oxygen in the exhaust gases after the converter.
How to check and replace the sensor
- This type of speed sensor is present in all VAZ cars
Check the continuity of the electrical circuit, because a break in it can lead to a malfunction of the DSA. Disconnect power. Inspect the contacts carefully. If there is oxidation or dirt, they need to be cleaned. Pay special attention to the wires located near the plug; they are bent in this place and can fray the insulation.
- We measure the resistance in the grounding circuit. Should be 1 ohm.
- If the circuit and resistance are normal, we check the operation of the DS itself.
The Lada speed sensor, installed on all AvtoVAZ cars, operates using the Hall effect, i.e. one full revolution is equal to 6 pulses. It has 3 contacts: ground, voltage, pulse signal. We ring the contacts for the presence of grounding and voltage (12 V). If the voltage is absent or less than 12 V, it means that either the power circuit is faulty, or the battery is discharged, or the ECU is broken. The output-to-ground voltage should be in the range of 0.5-10 V. The easiest way to check the operation of the device is to replace it with a properly functioning one.
To remove the DS you will need: a flat screwdriver, a 10mm wrench (ideally a head with a ratchet). In a Lada Granta car, the sensor responsible for speed is located extremely inconveniently, so replacing it is quite difficult. To improve access, first disconnect the thick pipe going to the throttle body from the air filter. Then:
- Disconnect the power plug from the DS. Bend the plastic retainer and immediately pull the shoe up to remove it.
- Unscrew the DS mounting bolt with a wrench.
- Pry up the DS body, because it is tight, and remove it.
We install a working speed sensor in the reverse order and carry out diagnostics.
Some car enthusiasts advise that after removing the DS, carefully inspect it, dry it and apply sealant around its perimeter. After this, reinstall the sensor. But it is better, of course, to replace it with a new one.
It must be remembered that erroneous data from the Lada Granta speed sensor can lead to significant malfunctions in the operation of the engine and vehicle components.
For the information of car owners of cars equipped with ABS: on your Lada, the DS on the gearbox is disabled, and the speed is read from the anti-lock braking system sensors.

Causes and their elimination
Why doesn't the speedometer work? The reasons may be the following:
- Rope break
- 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.
During repairs, you must use the parking brake or put the car in gear.
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?
To record the exact speed of movement, use the Lada Granta speed sensor (abbreviated as DS or DSA). It is located at the gearbox. Despite its small size, it is one of the main devices of the vehicle.
The Lada Granta engine management system is equipped with 7 main sensors: engine temperature sensor, oxygen sensor, speed sensor, as well as crankshaft position, phase, detonation and mass air flow sensors. The reliability and safety of the vehicle unit directly depend on the condition of these devices.
Everything the owner should know about the sensors and engine management system of the Lada Granta
To ensure the normal operation of all vehicle components, modern cars use many different regulators. In this article we will talk in more detail about domestic Lada cars. Where is the speed sensor, coolant and other controllers on the Lada Granta and what functions do they perform - read below.
Where is and how to find this or that regulator on Grant, Priora, Vesta or Largus? In fact, the location of the devices on these car models is identical. Below is a diagram identifying all devices.
Engine compartment Grants with the designation of all regulators
Speeds
The Lada Granta speed sensor is located on the gearbox housing. This regulator is directly related to the transmission of data about how fast the vehicle is moving, how the car is idling, and what kind of gas mileage it is driving at.
To find this controller on a Priora or Grant, you need to open the hood and remove the air supply hose that goes from the air filter element to the throttle. Having done this, at the bottom of the gearbox housing you can see the controller with a wire connected to it. To replace the device, you simply need to disconnect the wiring and remove it from the installation location, and then replace it with a new one.
DTOZH
Removing DTOZH from a car
A coolant temperature sensor is necessary to measure the temperature of antifreeze in the cooling system. In accordance with the data from the temperature regulator on the Grant, the control unit adjusts the crankshaft speed, adjusts the composition of the combustible mixture, as well as the ignition timing.
As practice shows, such a device rarely fails, but in some cases it can give incorrect readings. Located in the engine compartment, in particular, in the thermostat cover, the controller has its own “diseases”. The wiring at the base of the connector may fray, resulting in the need to replace the DTOZH.
Mass air flow sensor
The mass air flow controller is located behind the air filter element of the power unit, it is also often called a flow meter. The main purpose of the device is to monitor the volume of air flow that enters the vehicle engine. In accordance with the data received, the on-board computer determines the required volume of gasoline, which is necessary to maintain a normal air-fuel ratio.
XX
The idle speed sensor is one of the regulators designed to monitor and control the operation of the power unit. If the device breaks down, the motor immediately begins to work incorrectly - it will trip and the power will decrease. In turn, the needle on the tachometer will jump sharply from one value to another. The element itself is located on the throttle, in particular on its lower part. To get to it, you need to free the throttle valve from the pipes, there are four in total.
To replace and install a new IAC, you will need to disconnect the wiring from the regulator itself, as well as the throttle position controller. More detailed instructions for replacing the controller yourself are given in the video below (the author of the video is the channel In Sandro's Garage).
Sveta
As for the light sensor, it is installed in the same housing with the rain regulator. Its purpose is to activate and deactivate lighting based on the current state. For example, if it gets dark outside or you enter a garage or poorly lit tunnel, the device should automatically turn on the headlights along with the side lights. The controller itself is not repairable, so if it fails, the only option is to replace it.
Clutches and brakes
The clutch sensor allows you to determine the position of the pedal. When the pedal is not depressed, the regulator turns off the load adjustment on the power unit. The device is located in the pedal assembly, in the same place where the brake sensor is located.
The operating principle of the latter is quite simple:
- when the pedal is released, the rod is located inside and clamps the floating contact to the top;
- when the pedal is depressed, the rod clamps the contact to the bottom of the group.
As practice shows, one of the main problems of this controller is the poor quality of the contact itself. It can simply catch on the spring, and ultimately the control unit will receive an impulse to apply the brake.
Sorry, there are no surveys available at this time.

Lada Granta speed sensor operating principle. The speedometer on the Lada Granta does not work
A speed sensor is used to determine the speed per unit time. Many people are wondering where it is? And the speed sensor located on the transmission unit of the Lada Granta. This device, despite its modest size, is one of the main diagnostic elements of the car, so it is important to know its location.
The engine control system on Lada Granta models includes seven primary sensors that provide monitoring and control:
- engine temperature parameter;
- the amount of oxygen in the exhaust system (lambda);
- fixing the speed indicator;
- crankshaft position;
- valve timing;
- detonation process in cylinders;
- mass flow rate of intake air.
Every driver should know where these sensors are located. The proper operation of these sensors on the Lada Granta allows the engine to function normally.
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.
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:
Please note that unstable engine idling and increased fuel consumption can 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. They operate on the same principle and are interchangeable. The control oxygen sensor monitors the adjustment of the composition of the air mixture supplied to the injectors. The diagnostic oxygen sensor signals the presence of oxygen in the exhaust gases after the converter.

A speed sensor is used to determine the speed per unit time. Many people are wondering where it is? And the speed sensor located on the transmission unit of the Lada Granta. This device, despite its modest size, is one of the main diagnostic elements of the car, so it is important to know its location.
Checking the performance of the speed sensor
Considering where the Lada Granta speed sensor is located, the main malfunctions are associated with poor contacts in the electrical circuit or its rupture due to oxidation. Therefore, checking the speed sensor should begin by checking the condition of the contacts. To do this you should:
- disconnect the wires from the speed sensor;
- inspect contacts;
- clean dirt and oxides (if any);
Attention: the wires near the speed sensor plug are bent, so the insulation may fray in this place, leading to a short circuit.
- measure the resistance of the sensor grounding circuit (the norm is 1 ohm);
- eliminate problems in the grounding circuit (if any);
- check the presence of supply voltage at the sensor.
If the electrical circuits are working properly, the fault lies in the speed sensor itself.
When the power is connected (12V), the voltage at the output should be in the range of 0.5-10 volts.
Error code for speed sensor malfunction on Lada Granta: P0500.
A faulty Lada Granta speed sensor cannot be repaired and requires replacement.
What is needed to replace the Lada Granta speed sensor
To change the speed sensor, all you need is a screwdriver and a 10mm wrench. It is better to use not a wrench, but a socket with an extension and a ratchet.
A new speed sensor is also needed.
Replacing the Lada Granta speed sensor (VAZ Granta)
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.
What speed sensor is on the Grant?
Initially, the Lada Granta at the factory was equipped with three types of sensors: • Speed sensor VAZ-2170 PEGAS • Speed sensor Lada Granta 2190 AVAR Russia • Speed sensor 21700-3843010-02 All sensors have their own markings, so you can’t go wrong when replacing them.
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.
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.
- Flat screwdriver;
- The key is "10".
If you still have questions about this operation, you can always ask them on our forum. Also pay attention to other useful articles in our Lada Granta manual transmission section.
Car : Lada Granta. Engine : 21116. Asks : 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
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.
- 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.
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!
Why does the speedometer break?
It is worth noting that in some cases it is not difficult to repair the speedometer yourself. In others, you will need the help of specialists.
Thus, oxidation of contacts is considered a fairly easy to fix fault. It is characterized by the “jumping” of the arrow, despite the fact that the speed of movement remains stable. The problem is resolved by cleaning the contacts.
The wires are frayed. This reason can be suspected by the chaotic movement of the needle when starting the engine. Meanwhile, experts note that sometimes the problem does not manifest itself for a long time. It can be identified using a tester.
Sensor failure. A speed control device whose performance is questioned is replaced with a known good one. If the speedometer begins to function normally after this procedure, then there is no point in further looking for damage. Often sensors become unusable after their housing is destroyed and water or dirt gets inside.
Connectors. They are located in the VAZ-2110 in a place where they are constantly exposed to dirt. As a result, the contact is broken and the speedometer needle moves chaotically. The connectors must be completely cleaned and the connection must be checked for reliability.
Often the speedometer also begins to malfunction due to shaft wear. In this situation, it will be possible to get rid of the problem only after completely replacing the above-mentioned part.
As you know, the manufacturer installs an electronic speedometer on this model. If it has become unusable, then this problem is quite serious, since the above-mentioned device itself is not for sale. For this reason, you will have to buy a whole shield. However, in fact, in nine out of ten cases the problem is in a completely different place.
On a VAZ-2110 with an 8-valve engine, the speedometer receives information from the speed sensor. It, in turn, is located in the gearbox. There, through two gears, it receives torque data from the gearbox shaft.
Everything works similarly for cars with 16-valve engines.
Most often, as noted above, the problem is that the sensor is too dirty. In general, dust always accumulates under the hood of the VAZ-2110. It, when mixed with oil, creates a fairly stable barrier. As a result, the reliability of the speedometer readings becomes unconditional. The problem is easily solved - the sensor is cleaned and dried.
It is worth recalling that it will be more convenient to access it directly through the gearbox, since doing this from below is very inconvenient.
Another very common reason is problems with the electrical network. It all needs to be checked. In addition, attention is also paid to:
- reliable fastening of wiring in terminals;
- their general condition;
- fuses located within the mounting block.
In a situation where no damage to the electrical network is detected, you will have to take on the sensor itself. Its breakdown is the third most common cause of speedometer failure. It is checked in the following sequence:
- the sensor is removed from the gearbox;
- a drill or a screwdriver is applied to the drive, switched to the unscrewing mode;
- the ignition turns on;
- By pressing the drill button, rotate the drive.
In a situation where the speedometer needle begins to move, it should be recognized that the monitoring device is fully operational. This means one thing - the fault lies somewhere in the gearbox. Here, only an experienced car enthusiast or a professional locksmith can fix the breakdown on their own. When the arrow does not move, it will be enough to replace the sensor itself.
