Front ABS Sensor

Did you know your maximum braking power is just BEFORE you lock up your brakes and skid? ABS (Anti Lock Brakes) has been an incredible development in braking technology as it accomplishes just that - maximum braking and no skidding. The ABS wheel speed sensor is an integral part of that ABS system in that it measure wheel speed so that the ABS computer can quickly adjust brake pressures to THAT wheel for maximum braking power. Its a true life saver, so if its faulty, replace it soon for your own safety.

ABS Wheel Speed Sensor

A wheel speed sensor, also known as an ABS wheel speed sensor, is part of your vehicles anti lock brake system. The wheel speed sensor measures the exact speed of a corner of your vehicle. In total all vehicles with an ABS system will have four sensors. The wheel speed sensors are also used as reference points for traction control as well as stability control.

The wheel speed sensor measures wheel speed via a reluctor wheel or magnet located near the wheel hub. On some vehicles the reluctor can be part of the wheel bearing or it may be present on the wheel hub or axle. In some cases, a bad wheel bearing can be the cause for an ABS fault so it's recommended to do a full diagnoses on the ABS system and correlated parts before going into a repair

Depending on the vehicle the ABS wheel speed sensor may be a serviceable item or it may be part of a wheel hub assembly. In either case, a failed ABS wheel speed sensor will cause the ABS system to stop functioning and will also likely cause other systems such as traction and stability control to not function as well.
