Wheel Speed Sensor: Description and Operation

NOTE:  Any time an anti-lock brake sensor is removed, thoroughly clean the mounting surfaces. On front anti-lock brake sensors, apply High
Temperature 4x4 Front Axle and Wheel Bearing Grease E8TZ-19590A or equivalent meeting Ford specification ESA-M1C198-A.

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.
