The main reason for the failure of the VAZ-2110 electronic speedometer is a malfunction of the speed sensor, which will be replaced with a new one. Usually this failure is also accompanied by the CE indicator (check engine). However, there may be another cause of the non-working speedometer: damage to wires coming from the general tourniquet to the sensor. Most often, these wires can be rotting over time, so you need to check their status from time to time.
