A couple of days ago I noticed this thing 1-2 times a day - I was standing at a traffic light, the speed was zero, and the speedometer needle jumped to 20-30 km/h.
2 days after the needle jumped again, it went to zero and never got up again. As is already clear, the speed sensor died.
The symptoms are:
1) The speedometer needle jumps or does not show speed at all 2) The odometer does not show mileage 3) Engine error (check light is on) 4) EUR error and failure
Cause:
leakage of the contact connection, water ingress on the sensor contacts. Therefore, sensors often fail in wet weather (this is exactly the weather that was observed a couple of days ago, before frost - there was water and dirt on the road).
Replacing the sensor is not difficult; the work takes 10-20 minutes. It is necessary to turn off the ignition, remove the air filter pipe, disconnect the wire going to the sensor, unscrew the sensor nut with a 10 mm wrench, remove the old one, install the new one and reassemble in the reverse order. Sometimes cleaning the sensor contacts can help (if it helps, it won't be for long). The junction between the sensor and the gearbox can be coated with sealant to prevent similar problems in the future.
It is important that you first remove the sensor to check the markings on its body, because There are 3 varieties of viburnum: 1 — 1118-3843010 2 — 1118-3843010-02 3 — 1118-3843010-04
I had the last option, so I bought it.
After replacement, the engine light should go out, but if this does not happen, disconnect the battery, everything will be fine.
Signs and causes
The speed sensor is the main cause of speedometer malfunction.
There are several reasons why the speedometer needle starts jumping. On older generation cars, this is usually due to a drive cable or a malfunction of the dashboard itself. But Kalina has an electric drive, so here everything is a little different.
Signs of a malfunction may include not only the needle jumping, but also its freezing in a certain position. Usually, motorists remove the “minus terminal” to reset the system, but this does not always help, so they have to resort to more radical measures.
So, let's look at the reasons for the malfunction of the jumping speedometer needle:
- The motor in the dashboard has failed.
- Broken wires going from the instrument cluster to the speed sensor.
- The speed sensor has failed, which is considered the most common malfunction. The speed sensor is located under the hood of the car.
The speedometer of Lada Granta, Priora and Kalina does not work: reasons and why the instrument needle jumps
Experience shows that many Lada Kalina owners are faced with the concept of a jumping speedometer needle. This is due to several reasons. Some can be fixed on your own, but some will require knowledge in auto electrics.
- 1 Symptoms and causes 1.1 Troubleshooting
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.
Causes
Before you begin repairs, you need to determine why the speedometer is not working. All repair actions will depend on the cause of the breakdown.
One of the most common causes of speedometer failure is a broken cable. Such a breakdown is easy to detect - the steel ends of the cable touch the shell when the car is moving. Because of this, a characteristic sound is heard in the area of the shield.
Another cause of malfunction may be blown fuses. Poor contact connections can also lead to damage to the speedometer. Perhaps the reason is not serious. For example, a broken arrow can also distort the readings or not give them at all. In this case, it is enough to just replace one part.
Please note that due to the peculiar location of the speedometer in this Lada car model, the cause of failure is often water or dirt that gets into it. In this case, if the damage is not too severe, it will be enough to dry and clean it.

- Broken wires going from the instrument cluster to the speed sensor.
- The speed sensor has failed, which is considered the most common malfunction. The speed sensor is located under the hood of the car.
Debugg
When all the reasons have been identified, repairs can begin. First, as experience shows, it is necessary to replace the speed sensor. How to do it? Let's look at the step-by-step instructions:
- We find the sensor itself. It is located at the checkpoint.
- Replacement will take about half an hour, as well as a 10mm socket and two screwdrivers (phillips and flathead).
- In the engine compartment we find the air duct for the air filter element.
It will need to be dismantled. Unscrew the air filter duct clamp - We find the sensor and disconnect the wire connector.
Disconnect the speed sensor wires - Unscrew the sensor nut.
The place is the most inconvenient, and therefore you will have to suffer to dismantle it. Unscrew the nut securing the speed sensor - We are replacing the sensor.
To do this, you need to pry it out with a screwdriver. Pry up the sensor with a screwdriver and remove it
Now, the speedometer needle should not jump. But, if this does not help, then you need to look for the reason elsewhere.
As a rule, this may be a broken wire between the dashboard and the sensor. Using a tester, you need to ring the wires and make sure there is no break.
Main symptoms and causes of failure
This happens both while driving and when the car is simply standing still. For such a malfunction to make itself felt, it doesn’t matter how long the car has driven.
Also, in some cases, a sensor may light up, which indicates a malfunction of the power steering. It would seem that these malfunctions have nothing in common, but the speed of a car has been measured electronically for a long time.
Speed sensor
Thanks to electronics, the car can regulate the fuel supply itself. The sensor operates based on the Hall effect . It transmits rotation impulses from the wheel to the controller. If the car is coasting and the speed is no more than 20 km. hour, the system will automatically stop supplying fuel.
Symptoms of a speedometer failure on a Priora
A car speedometer is necessary to measure speed, as every driver knows. From this we can conclude that its failure is diagnosed due to one of the following problems:
- When the car is moving, the speedometer needle does not deviate from zero;
- The speedometer incorrectly detects the vehicle speed or turns off during operation.
Most often you come to deal with the second option of speedometer failure. A typical problem for Lada Priora cars is a temporary failure of the speedometer, when while the car is moving the needle drops to zero, an exclamation mark lights up on the dashboard and the electric power steering also fails. After a few minutes, the problem disappears and the car’s electronics operate as before.
Please note: Lada Priora cars are equipped with an electronic speedometer, as a result of which there are two options for failure: mechanical or electronic, that is, a failure of the microprocessor that controls the device.
Replacing the speed sensor, symptoms of failure
The main symptoms of a speed sensor failure on Kalina:
- The speed is not shown (the arrow is lying).
- Sudden jumps in the speed indicator, dips.
- The speed needle freezes, even when the car is stationary.
- The electric power steering fault light is on and the speed is not displayed.
The main problems may be 2 or poor contact in the plug (possibly oxidation), or the sensor itself is to blame (failure).
The sensor itself is located on the box and is screwed on with one nut.
A closer view of the sensor itself.
On cars with a 16-valve engine, access is convenient from the washer fluid reservoir; you don’t need to remove anything. On 8 valve engines, it is better to get there from the right side by removing the corrugation going from the engine filter to the damper.
First of all, it is better to check the connector to the sensor itself; to do this, we snap it out and look at the wires; if there is oxidation or foreign liquid, then clean it and insert it back. After that we check the work.
If cleaning does not help, then the sensor itself needs to be changed. We snap off the wire, unscrew one single 13 nut and clean everything around the sensor so that dirt does not fall inside the box.
Carefully remove the sensor itself with force by hand; if it is difficult with your fingers, you can help with a flat screwdriver.
We definitely pay attention to the sensor number , if the first digits are 1118, then you only need a sensor with the beginning of 1118, the last two digits may be different. Since 2011, AvtoVAZ began installing boxes on Kalinas like on Priors, and their sensors already come with a code at the beginning of 2170 .
It is better to remove the sensor in advance and look at the number, then buy it in the store.
Installation of a new sensor is carried out in reverse order.
Speedometer does not work on Kalina: recommendations
Problematic case: the speedometer does not work on the Lada Kalina
Very often you can hear the same phrase from Lada owners: the speedometer on Kalina does not work. The main reason for the failure of the speedometer installed on the Lada Kalina, judging by the reviews of car owners, is the incorrect operation of the speed sensor (DS). This malfunction is characterized by a variety of symptoms. Sometimes the speedometer needle on Kalina just calmly shows zero, sometimes it jumps like crazy.
In some cases it starts to freeze. This can happen both when the car is moving and at rest. For such a breakdown, the mileage is not at all important. Sometimes the EUR signal may come on. Most often, this means that the electric power steering in the Lada Kalina car has failed. It would seem that the steering wheel and speedometer readings are completely incompatible things. But the speed of a car has been measured electronically for a long time.
All readings are carried out by a speed sensor operating on the basis of the Hall effect. The controller receives electromagnetic pulses from this sensor. They are the basis for measuring the speed of a car. This sensor also saves fuel. If the car is coasting and the speed exceeds 20 km/h, the controller, reading the sensor readings, stops the fuel supply.
Characteristic signs of device failure and its replacement
Lada Kalina is equipped with different sensors, but they all have the same seats. Sensors are marked with numbers:
When this sensor fails on a Lada Kalina or Lada Granta, the speed of the vehicle cannot be measured. This also causes deterioration in engine performance. Most often, a complete replacement of the sensor is required for the following faults:
- when driving, the speedometer needle jumps or just lies quietly without moving;
- The electric power steering stopped working;
- the “check engine” light is on;
- the speedometer does not count mileage;
- The arrow indicating the fuel level twitches.
There are many reasons why the speedometer does not work. The first place is always a breakdown or failure of the speed sensor. Another reason could be a wet chip. Contacts begin to oxidize due to moisture. To protect the sensor, it is recommended to cover the top surface with sealant. When poor performance of the DS is detected, you should not immediately change it.
First you need to make a diagnosis. It is necessary to clean the contacts and test the device. If this does not help, you can proceed with replacement. Changing the element in question is quite simple. Any car enthusiast can handle this. Usually such work is completed in half an hour. To do this you need:
- turn off the ignition;
- remove the air filter;
- disconnect the wires;
- unscrew the nut securing the device;
- attach the new device.
In some cases, simply cleaning the contacts helps. However, this is a temporary salvation. After a few days the sensor will fail again. To avoid such problems, you need to properly seal the place where the device is connected to the gearbox. The element is attached to the gearbox housing. It is located near the left CV joint.
When the Lada Kalina is equipped with a 16-valve engine, the sensor is very easy to change. This operation will take a little time. If an eight-valve engine is installed, to replace the device it is necessary to remove the corrugation that is connected to the air filter.
Every car enthusiast knows well that car components are not always in perfect condition. Therefore, before installing a new part, you need to disconnect the wire block and check the condition of the contacts.
The sensor installed at the factory has a marking starting with the numbers 1118. However, since 2011, Lada Kalina began to be equipped with gearboxes that are installed on the Lada Priora. The marking in this case begins with different numbers, 2170. The built-in fuse that protects the electrical circuit of the installed instrument panel is designated F1. They will be equipped with a mounting block. When the fuse is lit, the speedometer stops working.
If the instrument panel is faulty
Very often, in addition to a broken speed sensor, a blown fuse designated F1, or poor wire contact, the speedometer installed on the Lada Kalina refuses to work because the instrument panel has failed. It can only be replaced as an assembly. The spare parts store does not sell individual parts of the instrument panel.
However, before proceeding with the replacement, you first need to make sure that the wire going to ground is securely fastened. Perhaps this is the reason for the breakdown. Of course, the design of the speedometer is based only on electronics, but motorists can cope with some of its malfunctions on their own. To locate the sensor under the hood and replace it, you must first perform several operations.
Why the speedometer on the Lada Kalina does not work: the main reasons and malfunctions
If the DS is faulty, then the following signs appear:
The listed symptoms can be caused by a breakdown of other devices (the author of the video is Autoelectrics HF).
Causes of breakdowns
The cause of the DS malfunction may be:
The first three reasons can be corrected without replacing the DS; in the latter case, the device must be changed.
The Lada Kalina speed sensor consists of a plastic housing shaped like a cylinder and an electronic sensitive element.
The place where it is located in the engine compartment is not difficult to find. To do this, you need to lift the hood to gain access to the engine compartment. The air pipe connects the throttle to the filter. After unscrewing the clamps, you need to dismantle the air pipe. On top of the gearbox is the DS.
Before changing the DS, you should first carry out a number of preventive actions that can eliminate the malfunction:
The sensor should also be removed, cleaned and checked for functionality.
The check can be performed in three ways:
The listed DS speeds can replace each other. They can be installed on the following versions of Kalina: 1117, 1118 and 1119 with 1.4 and 1.6 liter engines. The sensor from Lada Priora is suitable, but it cannot be used as it gives incorrect readings.

Speedometer does not work on Priora: reasons
If the speedometer on a Lada Priora car does not work, the first thing you should do is make sure that the problem is not related to bugs in the chip on which it operates. During operation, the chip's cache may become clogged with information, causing the speedometer to malfunction. To reset the speedometer chip settings, you need to reset the ground from the car battery and disconnect the power from the car's on-board network. Such simple manipulations will lead to resetting the settings of storage devices, including the speedometer chip.
The speedometer on Kalina does not work. Why?
One of the many “diseases” of the Lada Kalina car is problems with the speedometer on the dashboard; sometimes it simply does not work. Messages regularly appear on forums about “why the speedometer on a viburnum does not work.” Today we will look at the main reasons for the malfunction of this unit in a car.
The most common reason for a non-working speedometer on a Lada Kalina car, as it turns out from Internet forums, is a failure of the speed sensor. There are several signs of this problem. The speedometer needle can lie at 0, not moving at all, but sometimes it jumps like a mountain goat.
Sometimes it freezes, and it doesn’t matter to it whether the car is moving or not. It also happens that the ESD warning light comes on, but this only applies to those Lad Kalinas where an electric power steering is installed. Drivers who find themselves in this situation cannot yet understand why this happens, because the steering wheel and the speedometer are two different things.
The failure of the speed sensor occurs due to the leakage of its housing. As a result, water or oil begins to get inside. The sensor is located on the gearbox housing, not far from the left inner CV joint. From under the hood, on 16 valve engines, it can be easily removed and a new one installed. It will take no more than 5 minutes. But on 8 valve engines, in order to get to it, you will have to remove the corrugation coming from the air filter. But, unfortunately, spare parts are not always supplied with serviceable sensors, and they have to be sorted out. Before replacing the sensor, unclip the wire block that goes to the sensor and check the condition of the contacts.

Why does the speedometer not work?
There are several reasons for this phenomenon:
1. The speed sensor has failed
2. The speed sensor drive is worn out
3. Bending of the gear teeth of the speed sensor drive in the gearbox. Occurs less frequently than other causes, but still occurs
4. Malfunction of the instrument panel
5. Wiring fault.
As you can see, there are quite a few reasons. Moreover, the first three points are in one place (checkpoint), and the instrument panel is completely different. And all this is connected by meters of wiring and several connectors.

Profile pipes are common in industrial and private construction. They are used to construct outbuildings, garages, greenhouses, and gazebos. The designs can be either classically rectangular or ornate. Therefore, it is important to correctly calculate the pipe for bending. This will preserve the shape and ensure the structure’s strength and durability, on the website https://avtoindustriya.com/gruzovye-avtomobili/gruzovye-avtomobili-kitay/faw/. replacing pads on a Priora
Metal has its own point of resistance, both maximum and minimum.
Maximum load on the structure leads to deformations, unnecessary bends and even breaks. When making calculations, we pay attention to the type of pipe, cross-section, dimensions, density, and general characteristics. Thanks to this data, it is known how the material will behave under the influence of environmental factors. Kalina, speedometer sensor
We take into account that when pressure is applied to the transverse part of the pipe, stress arises even at points distant from the neutral axis. The zone of most shear stress will be the one located near the neutral axis.
During bending, the inner layers in the bent corners are compressed and reduced in size, and the outer layers are stretched and lengthened, but the middle layers retain their original dimensions after the end of the process.

The speedometer needle jumps and twitches
In this situation, the diagnostic adapter will once again help us. It costs a penny, but with the right approach it often helps out.
How can the adapter help us?
The bottom line is that on cars with an engine management system, the signal from the speed sensor is supplied in parallel to the instrument panel and to the engine control unit (ECU). And in some cases, to the ECU, and from the ECU to the instrument panel.
Here I drew it in red for clarity
And as I always say, when we connect the adapter to the diagnostic connector, we begin to see everything “through the eyes of the computer.”
Therefore, it is no longer difficult to guess how to determine the direction of searching for the cause of the jumping speedometer needle.
A man is driving and watching the speedometer. I sit next to you and monitor the speed readings in the diagnostic program.
If the speedometer needle jumps, but the speed graph in the program is smooth, then the problem is in the direction of the instrument panel.
And if the arrow twitches, and the graph also has “dips,” then the problem is in the direction of the speed sensor and its drive.
This is exactly what happened in our case. These dips mean an unstable signal from the speed sensor.
This means that there is no point in going into the instrument panel. You need to move towards the speed sensor.
Repair
Without correct determination of the cause of the breakdown, repair is impossible. Therefore, once again make sure that you have carried out a thorough diagnosis.
To repair, in most cases it is necessary to remove the speed sensor. If it is the problem, first clean and dry it, then put it back in place and check it. In addition, it is recommended to carry out a test with a temporary connection of a working sensor.
Carefully inspect all contact connections - if they are covered with dirt or rust, this may be the cause of the speedometer failure. In this case, they need to be cleaned.
If the reason is a frayed or dry speedometer cable, you will have to replace or lubricate it accordingly.

Before replacing the sensor, unclip the wire block that goes to the sensor and check the condition of the contacts.
Let us recall that in the previous article we looked at how to install fog lights on a Grant with your own hands. Be careful, there is a very scrupulous process for connecting the PTF.
If the sensor was original, then be sure to look at its markings, it should start with the first four digits 1118, but in 2011 they began installing gearboxes from Priora on Kalina.
On these boxes, the speed sensor marking will begin with the numbers 2170. The electrical circuit of the instrument panel is protected by a fuse designated F1, it is installed in the mounting block.
If it fails, the speedometer will not work.
In addition to the speed sensor, fuse F1 and wire connection blocks, the speedometer malfunction on the Lada Kalina may also be in the instrument panel itself. It is supplied as spare parts only in a complete set. But if you decide to replace the shield, first check the fastening of the ground wire coming from it. Maybe this is the cause of the malfunction.
Although the design of the speedometer is entirely based on electronics, malfunctions that arise during its operation can be eliminated by the driver himself.

Alexey: I had this, you can remove the tidy, remove the protection from it, well, the needles are balanced there, if it falls off, then put it in place and that’s it.
Oleg: my father had this, the car traveled 2800 km and the needle also jumped, then lay down, then started jumping again! here 1st maintenance came up, it turned out to be a tourniquet! We disassembled the harness and it turned out that 1 wire had come loose, replaced it and everything was fine! They will replace it under warranty! I also thought the speed sensor turned out to be simple!
Andrey: well, in short, it’s a speed sensor. can be changed simply, costs 450 rubles or under warranty, fails due to moisture or oil getting into it.
The reason for the speedometer not working
It didn't take long to find the reason. After removing the speed sensor everything became obvious
As you can see, severe corrosion led to the fact that the third contact rotted away completely. This was caused by a previous incorrect repair. Apparently, the connector had an unreliable contact. And instead of replacing the connector or repairing it, a piece of copper wire was inserted into it
This did not allow the connector to be hermetically connected and the moisture quickly took its toll. Here is the third contact removed from the connector
In general, everything was resolved by replacing the speed sensor and treating the connector with contact agent
Well, the process of replacing the sensor is a completely different story, which you can read about here.
