Was bedeutet der Fehlercode?
The ECM monitors the clutch pedal sensor and sets the code when the signal from it is faulty. The code indicates a fault in another control module, so fix that fault first; the code can be cleared once it is done. The clutch pedal sensor and its signal wire may also be the cause.
Mögliche Ursachen
- Signal wire shorted to supply voltage
- Damaged clutch pedal sensor
Was Sie tun können
- 1Read out the fault codes in the other control modules and remedy them first, since this code may be a follow-on fault
- 2If you have a diagnostic tool, watch the clutch pedal position in live data while pressing and releasing the pedal; the value should follow the pedal
- 3With the ignition off, use a multimeter to check that the signal wire from the clutch pedal sensor has no contact with supply voltage
- 4Clear the code only after the root fault is remedied, then road test the car and see whether it returns
- 5If it returns, the clutch pedal sensor is probably damaged; a workshop should decide whether to replace it
Symptome, die Sie bemerken können1
