The pedal position sensor is mounted on the power brake booster in the engine compartment. The sensor, which responds to the push rod for the pedal, is a sliding potentiometer. 0 mm corresponds to 0 V and 38.5 mm movement corresponds to approximately 95 % of battery voltage (Ubat ).
The pedal position sensor signal is used to check the function of the stop (brake) lamp switch.
The pedal position sensor is directly connected to the engine control module (ECM). This pedal position sensor has no ABS function.
