Speed ​​sensor Lada Kalina. Sensor number, causes of malfunction and replacement

A special sensor is responsible for measuring the speed of the car. It is he who transmits information to the ECU and thanks to this sensor we see the speed of our car. If you suddenly notice that the speed on the speedometer is lower than that of your car, the sensor may have failed and needs to be replaced.

You can replace the speed sensor on Kalina yourself, without the help of specialists, and we will describe how to do this below.

Which one is installed and where to find the speed sensor on Kalina

Lada Kalina cars are equipped with a speed sensor 1118-3843010 . It is located on the top of the gearbox, and to get to it, you need to unscrew the air pipe running from the filter housing to the throttle body.

How much does a speed sensor cost for Kalina?

Today there are several types of sensor 1118-3843010 from different manufacturers.

1. Sensor 1118-3843010 without ring (Pskov) price from 350 rub.
2. Sensor 1118-3843010 without ring (StartVolt) price from 300 rub.
3. Sensor 1118-3843010 with ring (Pskov) price from 500 rub.
4. Sensor 1118-3843010-04 (JSC Account Mash) price from 300 rub.

In order to accurately determine which sensor you have installed, you need to remove your old one and look at the markings on it.

Basic faults

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

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

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

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

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

How to determine if the sensor is faulty

There are a number of signs by which you can determine that the speed sensor is faulty and requires replacement.

• Odometer doesn't count mileage
• The speedometer needle moves chaotically regardless of the vehicle speed
• Check Engine Light comes on while driving

These are the main signs that indicate that you cannot avoid replacing the speed sensor on Kalina.

After removing the sensor, you can inspect it and clean it, sometimes this “reanimates” it. Moisture or dirt may get into it, which leads to its unstable operation. The sensor terminal contact may also oxidize.

Signs of a malfunctioning speed sensor

If the DS is faulty, then the following signs appear:

• incorrect speedometer readings, the needle moves chaotically, complete speedometer failure;
• increased fuel consumption;
• The power steering refuses to work;
• the power unit check sign is on;
• The car odometer does not show mileage;
• the arrow indicating the fuel level fluctuates, making it impossible to correctly determine the level;
• the engine does not pull or has lost throttle response;
• The engine stalls at idle.

Instructions for replacing speed sensor 1118-3843010 Lada Kalina

So, we open the hood and see a rubber corrugated pipe running from the air filter to the throttle. To make it easier to replace the sensor, we will have to remove this pipe.

After removing the pipe, we see on the gearbox housing a sensor to which a block with a wire fits.

Carefully remove it from the sensor and unscrew it using a socket on the “10” bolt securing the sensor. For convenience, you can use either a small ratchet or an extension cord.

We check the sensor block and clean it if necessary. We take the new sensor, install it in place and reassemble it in the reverse order.

This completes the replacement process; no other actions are required.

Diagnostics

Checking the controller can be done in several ways; we recommend that you familiarize yourself with each of them in more detail. For the first two methods you will need a voltmeter.

First way:

1. First, the sensor must be removed. Find its installation location, disconnect the connected connector, unscrew the fixing nut and remove the device from the mounting location.
2. Then take a voltmeter and figure out the pinout of the connector. The connector has three contacts, the first of which is usually a positive contact, the second is an output signal, and the third is a negative contact. One of the tester probes should be connected to contact number 2, and the second probe should be grounded - connected to the engine body or car body.
3. Afterwards, you need to rotate the controller to determine whether there are pulses in the operating cycle and measure the output voltage. To do this, you need to install a piece of pipe on the sensor axis and rotate the device at a speed of approximately 3-5 km/h. The voltage and frequency in the tester depend on the rotation speed of the controller (the author of the video is Artem Kulzhanov).

The second diagnostic option is performed without dismantling the sensor:

1. You need to put the car on a jack. You need to jack up the front of the car so that one of the wheels is hanging out and not in contact with the ground.
2. After this, the tester probes must again be connected to the contacts on the device connector.
3. The hanging wheel must be rotated and at the same time monitor the readings on the tester display. If, as a result of rotation, voltage and frequency appear, measured in hertz, then this indicates the operability of the device.

There is another checking option; to perform it you will need a light bulb or control.

Diagnostics is performed as follows:

1. First of all, you should disconnect the plug and wiring from the sensor.
2. Using the control, you will need to find the plus and minus, before that you need to turn on the ignition.
3. Next, as in the previous method, you need to put the front of the car body on a jack and hang one wheel.
4. Now you should connect the control pin to the pulse contact of the sensor (usually it is the middle one) and rotate the wheel by hand. If at the same time the minus lights up on the control panel, this indicates that the device is working. Alternatively, instead of a control, you can use a light bulb with a connected wire, one of which is connected to the battery, and the second to the signal connector. If the light begins to blink when the wheel rotates, then the controller is working (video shot by Alex Kov).

Recommendations for replacing the speed sensor on Kalina

Do not rush to change the sensor immediately; it is quite possible that the contacts have oxidized or dirt has gotten into the block. You can also clean the sensor itself and reinstall it. Different versions of Kalina may have excellent sensors:

• 1118-3843010
• 1118-3843010-02
• 1118-3843010-04

All the above sensors are interchangeable! They are suitable for Kalina 1117, 1118 and 1119 cars with 1.4 and 1.6 liter 8 valve engines. The speed sensor from Priora is physically suitable, but it cannot be installed, as it shows incorrect values.

Now you know what to do if the speedometer on Kalina stops working, what is the reason and how to solve this problem yourself.

Removal and replacement instructions

To replace the device, you will need:

• two screwdrivers - with a Phillips and a flat tip;
• wrench or socket wrench 10;
• rag.

You will also need a new sensor - Kalinas may use different controllers, so before purchasing, find out exactly which one you need.

So, how to replace the sensor yourself:

1. First, you need to turn off the power to the device and put the car on the parking brake by lifting the lever in the cabin.
2. Open the hood. At this stage, you need to gain access to the sensor; for this, as we have already reported, you will have to remove the air duct going to the air filter. Alternatively, you can try to move it to the side. To remove, use a flat blade screwdriver to unscrew the clamps.
3. Having seen the controller at the installation site, you will need to disconnect the wiring connector connected to it.
4. Now take a wrench or socket and unscrew the nut that secures the sensor in its mounting location. The nut itself is located in an awkward place, so unscrewing it may take time. It may be that the nut is stuck to the mounting location, although this rarely happens. To unscrew it, treat the landing site with WD-40.
5. Then take a flat-head screwdriver and disconnect the device from the transmission, and then remove it. Using a rag, clean the installation area; this can also be done before removing the sensor. Clean the surface thoroughly to prevent dirt from getting into the box itself.
6. Now you can begin installing the new controller. Install the device and connect the connector with the wire to it. Don't forget to reinstall the air pipe.

How to identify a malfunction

Like any electronic equipment, the speed controller fails from time to time. How to determine the problem on a Lada Kalina car? Firstly, a breakdown in the sensor is reflected in the inability to determine the speed. If this is observed, then repair will no longer help; an urgent replacement of the part is needed.

Failure to display information is the last stage; in such a case, the device cannot be repaired. But how can you determine that a node is approaching the extreme limit of its performance? Possible signs of malfunction:

• interruptions in the Lada Kalina engine can indicate various problems, one of which is sensor failure;
• if increased fuel consumption is observed, this may also indicate a defect in the device in question;
• if there are interruptions in the pulses coming from the speed sensor, the power unit of the Lada Kalina cannot develop full power;
• unstable, stalling motion, decreased controllability and dynamics.

If the car belongs to the category of modern, highly equipped, then the sensor failure will be indicated by error code No. 24 displayed on the on-board computer, or the Check engine light will come on. In relation to Kalina, if the device breaks down, the electric power steering also refuses to work.

As a rule, breakdowns in the sensor occur for several main reasons. For example, as a result of an electrical circuit failure. This is why it is so important to regularly monitor electronics, as the most vulnerable system of a car. If any contacts become oxidized or even just a little dirty, this can also have a very negative effect on the operation of electronic devices.

To fix the problem, in this case you just need to clean the contacts and coat them with any special lubricant for electrical wiring, which can be purchased at car dealerships. Their cost is low, so such prevention is affordable for every car owner.

Purpose of the sensor

A modern car is a complex structure in which every working operation is strictly controlled by special devices. The same applies to speed measurement. If previously the speed of the car was measured mechanically, now this function is performed at a higher level by a speed sensor.

The speed sensor is a complex electronic device installed on the gearbox speedometer drive. Its task is to transmit the movement impulse to the controller and record the slightest changes in the movement of the car. Finding the sensor is not difficult, you just need to remove the adsorber. Here you can see the wire that goes to the transmission, it connects the transmission to the sensor.

As practice shows, the speed sensor also has another, secondary operating function - fuel economy. Of course, in small quantities. Fuel saving occurs when the Lada Kalina car is moving at a speed slightly above 20 km/h on the coast, then no fuel is supplied, and therefore no fuel is consumed.

How to replace the sensor?

Before installing a new sensor, you will need to dismantle the damaged part. To perform this manipulation, the owner will need to acquire a “6” key or a Phillips screwdriver.

Sensors have several design varieties, and each type of product is assigned its own code. This is important when selecting a similar component.

Replacing a speed sensor is not a complicated procedure, so any LADA Kalina owner can do it.

1. Unscrew the clamp screw.
2. We remove the corrugated pipe and press out the fixing element.
3. Remove the block with the supply wiring and move it to the side.
4. Unscrew the fasteners and remove the old sensor.

We carry out installation following the reverse algorithm of manipulations.

Symptoms of a faulty speed sensor

If your car has at least one of the following reasons during operation, this will be one hundred percent reason to check it.

• Unstable operation at idle.
• Fuel consumption has increased.
• The engine does not “pull” or is no longer as responsive as before.
• The speedometer does not work or there are errors in the operation.
• The electric power steering is turned off.

If an on-board computer is installed on the car, then errors coming from the speed sensor will also be a reason for checking.

Causes of malfunction

The most common cause of speed sensor failure is faulty wiring. It is highly exposed to external weather conditions, oxidizes and rusts. Thus, only an external examination will give the correct answer.

One of the sensor contacts has fallen off due to corrosion.

After the wiring and sensor are inspected, we proceed to dismantle it. How to properly carry out this operation is written in this article.
