Wheel speed sensors are often called ABS sensors. You'll find them mounted on the axles of all ABS equipped vehicles on your wheel hubs, near the brake rotors./The ABS sensor is a vital part of the braking system. Without a working ABS wheel speed sensor, the ABS system will fail to work properly. Resulting in a ABS Light on your Dash and loss of your Antilock Brake System.
