Code C0297:01 Description

The brake pedal position sensor is used to sense the action of the driver's application of the brake pedal. The brake pedal position sensor provides an analog 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 right and left stop lamp control circuits, Engine Control Module (ECM), and center high-mounted stop lamp relay control circuit. The Diagnostic Trouble Code (DTC) will be set when the BCM detects a short to voltage or an open/high resistance in the brake applied signal circuit.
