P057D Buick Code - Brake Pedal Position Sensor Circuit High Voltage
Quick Answer
The Brake Pedal Position (BPP) sensor is used to sense the action of the driver's application of the brake pedal. Common causes include Brake Pedal Position Sensor Calibration, Faulty Brake Pedal Position Sensor, Brake Pedal Position Sensor harness is open or shorted. Severity is High - diagnose this code as soon as possible. Driving is not recommended if the warning light is flashing, the engine runs poorly, or safety-related symptoms are present.
