Pedal Position Sensor
WARNING: This page does not describe the selected car, but rather 8 other vehicles, including the 2013 Volvo C70, 2012 Volvo C70, 2011 Volvo C70, 2010 Volvo C70, and 2009 Volvo C70. However, it is still accessible from the selected car via links, so may be relevant.
The pedal position sensor is mounted on the power brake booster in the engine compartment. The sensor has several functions.
The sensor is used:
- by the engine control module (ECM) for cruise control. The signal is transmitted via the controller area network (CAN)
- to shut off traction control during braking (TRACS AWD only)
- to diagnose the function of the stop (brake) lamp switch (TRACS AWD only).
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.
