An Anti-lock Brake System (ABS) Sensor (sometimes known as an ABS wheel or speed sensor) is a critical component of the anti-lock breaking system which helps prevent collisions. The anti-lock braking system uses an ABS sensor to monitor wheel speed. The sensors send information for each of the wheels to the ABS computer. The ABS computer determines if any of the wheels are locking up and pumps the brakes accordingly.

The ABS sensor is typically located in each wheel hub/rotor on a four-channel ABS system. Some rear wheel drive applications have the sensor mounted in the rear differential. These sensors can get clogged from metallic debris, brake dust or dirt due to exposure to harsh elements. Clogging can lead to failure, and failure may prevent the ABS from operating safely and properly.
