Wheel Speed Sensors

Print

Removal & Installation



Front

One wheel speed sensor is mounted to each knuckle. The wheel speed sensor, using a tone wheel attached to the hub and bearing (RWD) or front half shaft (AWD) as a trigger mechanism, communicates with the Antilock Brake Module, informing it of that wheel's speed.

The head of the front wheel speed sensor used on Rear-Wheel-Drive (RWD) vehicles mounts to the inside of the knuckle.

The head of the front wheel speed sensor used on All-Wheel-Drive (AWD) vehicles mounts to the rear of the knuckle.

Vehicles without antilock brakes are equipped with one front wheel speed sensor. It is attached to the right front knuckle and is used to provide wheel speed sense to various vehicle systems.
