- Use a non-metallic feeler gauge to measure the gap between the sensor and the pulser.
- Rotate the hub or axle slowly by hand, taking measurements at several locations.
Compare with the following specifications:
Removal & Installation
- Raise and safely support the vehicle as necessary for access.
Make certain the ignition switch is
- Detach the sensor harness connector.
- Beginning at the connector end, remove grommets, clips or retainers as necessary to free the harness. Take careful note of the placement and routing of the harness; it must be reinstalled in the exact original position.
Remove the bolt holding the speed sensor to its mounting, then remove the sensor. If it is stuck in place, gently tap on the side of the mounting flange with a hammer and small punch; do not tap on the sensor.
- Place the sensor in position; install the retaining bolts loosely. Route the harness correctly. Avoid twisting or crimping the harness; use the white line on the wires as a guide.
- Once the harness and sensor are correctly but loosely placed, tighten the sensor mounting bolts. Tighten bolts to 16 ft. lbs. (22 Nm) for 2001 models and to 7.2 ft. lbs. (9.8 Nm) for 2002-06 models.
- Working from the sensor end to the connector, install each clip, retainer, bracket or grommet holding the sensor harness. The harness must not be twisted. Tighten any bolt holding brackets to 84 inch lbs. (10 Nm).
- Attach the wiring connector.
- Carefully lower the vehicle to the ground.
