does abs sensor affect speedometer
No impact. The ABS sensor does not affect power. Damaged BS sensors can cause instrument malfunction lights to turn on and ABS to fail. Causing temporary failure of ESP and explosion-proof dead functions, but not causing interference to the power system.
ABS anti-lock braking system, as one of the most important safety systems in automobiles, was originally developed by Bosch and first used in large quantities on Mercedes-Benz. After years of development, ABS and ESP complement each other and have become indispensable safety equipment for cars. The main function of the ABS system is to prevent the wheels from being locked when the car brakes, and to avoid slipping and tail flicking. The ABS system generally consists of a control module, master cylinder, oil pipe and ABS sensor. As the most important sensor in the ABS system, there are four in the whole car, which are respectively installed near the bearings on the inner sides of the four wheels, that is, on the horns. The ABS sensor also has the function of tire pressure monitoring, which mainly appears on models with indirect tire pressure monitoring. Because indirect tire pressure monitoring uses the ABS sensor to compare the number of rotations of the four tires, if the air pressure of a tire is too high or too low, then its number of rotations will definitely be different. Generally speaking, after the ABS sensor is damaged, the driving instrument of the vehicle will have ABS fault lights, anti-skid fault lights, tire pressure fault lights and other fault phenomena, and relevant fault codes will be stored in each control module. In the process, it is difficult to feel what kind of problems will be caused by the damage of the sensor.
What is the reason why the ABS light is on and the odometer will still run? If the ABS light is on, it does not mean that the odometer will not run. If the ABS light is on, it can only indicate a malfunction in the ABS system, but it does not mean that the ABS system is completely unable to provide signals. Therefore, in this case, it is still necessary to read the fault code of the ABS system and repair it according to the fault code. This does not affect regular braking, and the car can still continue to run.
