Description

Front ABS wheel speed sensor, part of the four-wheel WABCO anti-lock braking system’s sensing circuit. Catalogued under a sensor kit part number; the assembly is the speed sensor with its integral lead and connector.

The sensor locates in the front hub carrier and reads the toothed exciter ring on the hub, supplying the wheel speed signal the ABS control module uses to detect impending wheel lock and modulate brake pressure at that wheel.

One sensor is fitted at each front wheel. The sensor tip and its seat in the carrier should be cleaned of corrosion and debris before a new unit is fitted.
