Driving dynamics control / ABS (ESP) sensor Information

How does the ABS sensor work? The ABS sensor is a sensor that is attached to the tires and forms the core of the ABS or ESP system. The sensor is attached to the tyre or in its vicinity, and monitors the tires and their movements during braking. If the wheels lock up, this is registered and passed on to the control box in the engine compartment through the ABS or ESP sensor. The braking action on the corresponding tire is reduced so that the tire is no longer locked up. Usually the sensor is able to detect a wheel locking before it begins and can prevent it from happening. If the sensor is damaged, it will no longer perform this task the ABS system will become ineffective or no longer function. Well-known manufacturers of sensors are MAPCO, DELPHI, NK, SWAG, METZGER, FEBI BILSTEIN and VEMO.

Lifespan of ABS Sensors

The ABS sensor does not count among the wear parts of a car. For this reason there is no specified lifespan or guidelines for problems with the ABS sensor. The sensors, as well as the whole system should be regularly checked and maintained, which generally occurs in inspections. In rural areas, where there are often high snowfalls and where the road surface is uneven, the risk of damage to the ABS sensor is greater than in the city. But generally it is only necessary to replace an ABS sensor if it is damaged and problems arise.

Inspecting and Replacing the ABS Sensor

The ABS sensor is a complex spare part which has an important role when braking. Along with mounting this part, it is also necessary to install and to adjust it. Replacing and Testing the ABS Sensor: this should always take place in a specialist workshop. It is not recommended to replace the ABS sensor yourself.

Signs of a defective ABS sensor

Generally if an ABS sensor fails there will be a warning light that is displayed on the dashboard. If the ABS or ESP warning light is lit up, the system is not able to be used and this should be looked at in a workshop. In addition, without the ABS system the driving and braking of a vehicle will change. The braking distance will become longer and the wheels could lock up.
