Sensor Replacement Guidelines

WARNING: This page is about a different car, the 2004 Pontiac Aztek and 2004 Buick Rendezvous. However, it is still accessible from the selected car via links, so may be relevant.

The SIS replacement policy requires replacing sensors in the area of accident damage. The area of accident damage is defined as the portion of the vehicle which is crushed, bent, or damaged due to a collision.

Replace the sensor whether or not the air bags have deployed.
Replace the sensor even if it appears to be undamaged.

Sensor damage which is not visible, such as a slight bending of the mounting bracket or cuts in the wire insulation, can cause improper operation of the sensor. Do not try to determine whether the sensor is undamaged, replace the sensor.
