ENGINE CONTROL COMPONENTS

Brake Pedal Position (BPP) Switch
The BPP switch is sometimes referred to as the stoplamp switch. The BPP switch provides a signal to the PCM indicating the brakes are applied. The BPP switch is normally open and mounted on the brake pedal support. The BPP switch is hardwired to the PCM supplying battery positive (B+) voltage when the brake pedal is applied.
