Code P057D Cadillac Description

The Brake Pedal Position (BPP) 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 Brake Pedal Position Sensor contains 2 potentiometer-type brake pedal position sensors. When the pedal is pressed, the voltage of one sensor goes up and the voltage of the other sensor goes down. The Diagnostic Trouble Code (DTC) will be set when the Brake Pedal Position Sensor is greater than 4.75 V for greater than 1 s.
