Ride Height Sensor: Service and Repair

When repair or adjustment procedures require that vehicle be raised on a hoist, it is important that the rear axle assembly remains in the normal trim height position at all times. When a frame contact hoist is used, two additional jack stands should be used to support the rear axle or control arms in the normal trim height position.

1. Disconnect battery ground cable.
2. Raise and support vehicle.
3. Disconnect harness from sensor electrical connector by squeezing oval sides of the connector lock to release locking tabs.
4. Remove link from height sensor arm, then remove sensor mounting screws or nuts and the sensor.
5. Remove sensor mounting bracket to underbody attaching screws and remove bracket.
6. Reverse procedure to install, noting the following:
a. When connecting harness to sensor electrical connector, push connector into sensor plug until sloped shoulder on rear edge of boss is visible in plug slot. Push oval connector lock onto plug until its two locking tabs snap over shoulder of sensor plug.
b. Perform height sensor operational check and adjustment procedure as described under DIAGNOSIS AND TESTING PROCEDURES/TESTING PROCEDURES/HEIGHT SENSOR OPERATIONAL CHECK and ADJUSTMENT PROCEDURES/HEIGHT SENSOR.
