Removal Procedure

Important:  The wheel speed sensor wiring is included in the engine harness. The wiring between the wheel speed sensor and the heat shrink sealed splices is high-flex cable and must not be repaired or spliced. This procedure replaces the high-flex cable with a jumper harness from a supplied repair kit.

1. Turn OFF the ignition.
2. Raise the vehicle.
3. Remove the left front tire and wheel assembly. Refer to TIRE AND WHEEL REMOVAL AND INSTALLATION in Tires and Wheels.
