Throttle/Pedal Position Sensor "C" Minimum Stop Performance
- Severity
- High
- Driving
- Drivable — book it in
Throttle or pedal position sensor "C" is not reading what the module expects at the closed end of its travel. The module learns where each sensor sits when the pedal is released and the throttle is at rest, and compares against it. A shifted minimum usually means carbon holding the throttle plate slightly open, or a sensor whose track has worn at the position it spends most of its life in.
Possible causes
- CommonFailed throttle or pedal position sensor
- CommonCorroded or damaged connector
- CommonWiring damage, particularly at the pedal where feet catch the harness
- CommonLoss of the 5 volt reference or the sensor earth
- PossibleCarbon on the throttle plate affecting the reported position
- PossibleSensor not calibrated after replacement
What you might notice
- Reduced power mode
- Hesitation or surging
- Engine not responding to the pedal
- Rough or unstable idle
- Warning light for reduced engine power
What to check, in order
- Inspect the throttle body for carbon holding the plate off its rest position.
- Watch all the pedal and throttle position readings together on the live data screen while pressing the pedal slowly through its full travel. The one that jumps, sticks or does not follow the others is the fault.
- Check the reference voltage and earth at the sensor. Several sensors usually share these, so a lost reference produces a scatter of codes from healthy sensors.
- Inspect the connector for corrosion and water, and the harness at the pedal for damage.
- Look for other codes sharing the same reference circuit before condemning this sensor.
- On most vehicles the pedal sensors are part of the pedal assembly and are not supplied separately - establish that before ordering.
