The pedal position sensor is mounted on the power brake booster in the engine compartment. The sensor has several functions.

The sensor is used:

The sensor is affected by the push rod for the brake pedal. It is a sliding potentiometer.

Fault detection of the signal is between 0 V-0.15 V and 4.85 V-5.0 V. A diagnostic trouble code (DTC) is stored If the signal is between 0 V and 0.15 V. The sensor is considered not to be installed in the car. If the signal is between 4.85 V and 5.0 V, the sensor is understood to be pushed in excessively.
