Caution: Be very careful when handling the sensors during service procedures. Never strike the sensors. Never jar the sensors. These actions could result in personal injury, or improper operation of the Supplemental Restraint System (SRS). Carefully tighten all of the sensors, and all of the mounting bracket bolts to ensure proper operation. Never power up the Supplemental Restraint System (SRS) when any one of the sensors is not rigidly attached to the vehicle. An unattached sensor could be easily activated causing the deployment of the air bag.

1. Disable the Supplemental Restraint System. Refer to Disabling the SRS .
2. Raise the vehicle. Refer to General Information in Section 0A.



3. Disconnect the Connector Position Assurance (CPA) lock from the retainer.



4. Disconnect the electrical connector.



5. Remove the mounting bolts.
6. Remove the sensor from the vehicle.

Important: Use the following repair procedures when the sensor mounting holes or fasteners are so badly damaged that the sensor may no longer be properly mounted.

First Repair
