Deceleration Sensor (AWD Vehicles Only): Notes
WARNING: This page is about a different car, the 2004 Pontiac Vibe. However, it is still accessible from the selected car via links, so may be relevant.
The EBCM uses a deceleration sensor to sense vehicle motion.
The EBCM provides power (5 volts) and ground to the deceleration sensor. The deceleration sensor sends a voltage signal back to the EBCM relative to vehicle motion. This signal is about 2.4 to 2.6 volts at zero speed change (constant motion) and stationary, the voltage signal decreases when the vehicle is under acceleration, and the voltage signal increases when the vehicle is under deceleration.
The deceleration sensor is located under the LH front seat.
