Code C0277 Saturn Description

The brake pedal position sensor is used to sense the action of the driver application of the brake pedal. The brake pedal position sensor provides an analogue voltage signal that will increase as the brake pedal is applied. The Body Control Module (BCM) provides a low reference signal and a 5 V reference voltage to the brake pedal position sensor. When the variable signal reaches a voltage threshold indicating the brakes have been applied, the BCM will apply battery voltage to the stop lamp control circuit illuminating the left and right stop lamps and the Center High Mounted Stop Lamp (CHMSL). The BCM also applies battery voltage to the transmission control module (TCM) and Engine Control Module (ECM) via the brake applied signal circuit.
