Position Sensor

Proper lifting equipment enables you to raise and support the vehicle for Electronic Suspension Rear Position Sensor replacement. Remove the tire and wheel. The ride sensor link must be removed from the upper control arm ball stud as well as the ride sensor harness connector. The rear ride sensor retaining nut requires loosening so you can tap the rear ride sensor retaining stud to break its connection with the frame. Complete removal of the rear ride sensor takes place from the vehicle. Install the sensor into its vehicle position while letting the captured stud rest at the lowest point in the keyhole. After seating the tab of the bracket into the slot on the sensor you should continue rotating both components until the sensor remains level. Fasten the rear ride height sensor retaining nut using 9Nm torque until it reaches 80lb in. The ride sensor link needs reattachment between the upper control arm ball stud and the ride sensor harness connector. To conclude the procedure you need to reinstall the tire and wheel then lower down the vehicle.

The correct first step to replace Electronic Suspension Rear Position Sensors involves lifting the vehicle using proper lifting equipment. The first step involves removing both tire and wheel followed by disconnecting the ride sensor link from the ball stud adjusted on the upper control arm and the ride sensor harness connector. Twist the rear ride sensor retaining nut then apply gentle taps to the retaining stud to break its binding with the frame surface. Extract the rear ride sensor through a series of steps from the automobile. Put the new sensor into place by letting the captured stud reach the keyhole base and turning the sensor and bracket until the bracket tab inserts properly into the slot. Adjust the sensor bracket until the sensor reaches level position by letting the captured stud rise above the keyhole. Secure the rear ride height sensor retaining nut at 9 Nm (80 lb in) and then attach the ride sensor link to the control arm ball stud together with the ride sensor harness connector. Complete the procedure by placing back the tire and wheel while lowering the vehicle.

The first step to change Ride Height Sensor and Bracket fittings at the rear involves lifting and sustaining the vehicle before tire and wheel removal. Detach the rear ride height sensor link from both the upper control arm ball stud as well as the rear ride height sensor harness connector. The rear ride height sensor retaining nut should be loosened before gently tapping the rear ride height sensor retaining stud so it can detach from the fender. Disconnect the rear ride height sensor that is installed on the vehicle. Place the sensor inside the vehicle while verifying that the captured stud reaches the lowest point of the keyhole. Continuously rotate the sensor along with its bracket until the bracket tab fully engages the slot structure. The sensor bracket needs further rotation until the captured stud lifts a little from its position in the keyhole for achieving sensor level. The rear ride height sensor retaining nut requires tightened to 9 Nm (80 inch lbs.) for installation. Connect the ride height sensor link again to the upper control arm ball stud and also to the ride height sensor harness connector. The vehicle should have its tire and wheel reinstalled afterward to enable lowering.

The replacement of Ride Height Sensor and Bracket at the rear begins with vehicle elevation and suspension followed by tire wheel removal. The technician must detach the rear ride height sensor link from both the upper control arm ball stud and the rear ride height sensor harness connector. Start by loosening the rear ride height sensor retaining nut while giving the rear ride height sensor retaining stud a light tap for breaking its fender connection. Take out the rear ride height sensor component from the automobile. To install the sensor, position it in the vehicle until the captured stud rests at the bottom of the keyhole while rotating the bracket so its tab fits completely into the groove. Adjust the sensor bracket level by allowing minimal upward movement of the captured stud from the keyhole until the sensor becomes level. Hook up the rear ride height sensor retaining nut then fasten it at 9 Nm (80 inch lbs.) following the Service Precautions Fastener Notice. After reinstalling the tire and wheel first, reconnect the ride height sensor link to the upper control arm ball stud as well as the ride height sensor harness connector before lowering the vehicle.

Loosen the rear ride sensor retaining nut and gently tap the rear ride sensor retaining stud to loosen the connection to the frame.

If the sensor bracket is not level, continue to adjust it until it is level.

Disconnect the ride sensor link from the upper control arm ball stud and the ride sensor harness connector.

Continue to rotate it slightly to achieve a level position.

Tighten it to 9 N.m (80 lb in).

Position the sensor in the vehicle, ensuring the captured stud bottoms out in the keyhole, and rotate the sensor and bracket until the tab on the bracket is fully seated in the slot.

Loosen the rear ride sensor retaining nut and gently tap the rear ride sensor retaining stud to loosen the connection to the frame.

Install the tire and wheel and lower the vehicle.
