A wheel speed sensor, also known as an ABS sensor, is an important part of the braking control system. Its main purpose is to detect the rotational speed of the wheels and feed this information back to the vehicle’s engine control unit (ECU). If you notice that the ABS light is illuminated on your vehicle’s dashboard or that your front tyres lock up when you apply your brakes - your wheel speed sensor could be the culprit. The cost of a repair will vary based on the make and model of your car along with the severity of the problem. At Parts for All Cars we have a multitude of low priced replacement options to get you safely back on the road.
