Code C0191 Buick Description

The ignition 1 circuit supplies 12 volts to the longitudinal accelerometer. When the vehicle is not moving, or is being driven at a constant, steady speed, longitudinal acceleration is 0 m/sec/sec (0 ft/sec/sec) and the longitudinal accelerometer signal voltage is very near 2.5 volts. This is referred to as longitudinal accelerometer bias voltage. Vehicle acceleration or deceleration causes the longitudinal accelerometer signal voltage to increase or decrease. The harder the acceleration or deceleration, the greater the change in signal voltage.
