Wheel Speed Sensor: Description and Operation
The anti-lock brake system uses three variable-reluctance sensors to determine vehicle speed. The anti-lock brake sensors operate on magnetic induction
principle. As the teeth on the anti-lock brake sensor indicator rotate past the stationary sensor, a signal proportional to the speed of the rotation is
generated and sent to the anti-lock brake control module through a twisted cable and shielded wiring harness.
The front anti-lock brake sensors are non-adjustable. The front anti-lock brake sensors and the front anti-lock brake sensor indicators are replaced
separately.
The front anti-lock brake sensors are attached to the front wheel spindles. The front anti-lock brake sensor indicators are pressed onto the wheel hubs.
The rear anti-lock brake sensor is located on top of the differential case. The rear anti-lock brake sensor indicator is located inside the rear differential
case.
