Safing Sensor


The safing sensor is part of the center console crash sensor on 1994-95 vehicles. On 1996-00 vehicles, the safing sensor is part of the air bag diagnostic monitor. The safing sensor operates identically to the crash sensors, except for the calibration. This is accomplished using a slightly weaker bias magnet. If the safing sensor contacts close simultaneously with the crash sensor, the air bag(s) will be deployed.

The safing sensor is essentially a safety for the air bag system. It protects the bag(s) from deploying due to an electrical short. The safing sensor is used to verify the force of a collision and complete the air bag(s) deployment. The sensor is located inside the passenger compartment so that a forceful enough impact could be detected, and a false signal from the crash sensor would not deploy the air bag(s) at an inappropriate time.
