The speed sensor on the "VAZ-2110": adjustment, removal and installation

When a speedometer goes out, most drivers immediately blame the speed sensor. Indeed, this device often breaks down, which is due to many factors. The principle of its operation is based on the Hall effect.

How to check the VAZ-2110 speed sensor

Before you perform a replacement, you need to make sure that the fault is exactly this device. Therefore, first we perform its verification. There are several ways to do this. From the tools you will need a set of keys and a digital voltmeter or any other device that allows you to measure the frequency of the current.

The first way we need to remove the device. Then the speed sensor on the VAZ-2110 should be checked. To do this, we connect a voltmeter to its contacts. Further, by rotating the sensor, we must obtain the output value in Hertz on the screen. If you start to rotate the rotor faster, the value should increase, if it does not, then something is wrong.

If we use the second method, then we do not need to dismantle the sensor from the car. But for this you need to install the machine on the pit and pick up one wheel, and then connect the voltmeter to the sensor connector. Try to rotate the car wheel and look at the resulting value.

Removing the speed sensor: step-by-step instruction

If after the diagnosis it turned out that the device is defective, then it must be removed. It is quite easy to do this. To do this, turn off the ignition and disconnect all wires leading directly to the sensor. Next, take the key to 22 and turn out the out of order device. Installation is carried out in the reverse order with the tightening torque not more than 10 Nm.

Often happens that at this time the drive shaft breaks off. In this case, you need to dismantle the speedometer drive. To do this, use the key for 10, If the device does not exit the socket, then slightly sway it. You need to be careful, since there is a possibility of getting the drive into the gearbox. Installation is in the reverse order. As you can see, there is nothing difficult. Doing all the work takes no more than 10 minutes.

Important information

Since cars produced by the Volzhsky plant are not sterile under the hood, external pollutants often cause the sensor to malfunction. Consequently, in some cases, a simple cleaning is sufficient. To do this, you need to visually inspect the speed sensor on the VAZ-2110. If it is susceptible to oil, dirt, working off, etc., we remove it. How to do this, we already know.

Then you need to clean it well, then reinstall it. If this did not work, then another reason is poor contact. It happens because of elementary corrosion. Another reason could be a wire break. In order not to worry, it's better to just buy a new device, especially as the VAZ-2110 speed sensor costs only 200-250 rubles. But first it is desirable to check if the speedometer is working, because sometimes it's all his fault.

Conclusion

We have figured out how to correctly replace the VAZ-2110 speed sensor. The sequence of actions must be observed and you should not try to remove the device when the engine is switched on or without disconnecting the wiring before it. It is also advisable not to smoke during the replacement and not to bring an open fire close to the car. All this is an elementary security measure that every car owner must follow, who has decided to perform an independent replacement.

In conclusion, I would like to note that the body of the device is made of plastic, so you need to be extremely careful during its removal, especially if you are not going to buy a new speed sensor on the VAZ-2110. If you find that the device does not respond, then repair it is useless, it is much easier to buy and install a new one, because it will be much faster and cheaper, especially if you do it yourself.
