What is a Wheel Speed Sensor?
Wheel speed sensors are often called ABS sensors. You’ll find them mounted on the axles of all ABS equipped vehicles. Look for this sensor on your wheel hubs, near the brake rotors.
You’ll find the rear wheel speed sensor mounted on the rear axle housing or wheel cylinder. 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.
