Checking the status
- Ignition on
- Read off the clutch pedal movement by carefully pressing and releasing the clutch pedal.
Check that the value changes with clutch pedal movement. The value must be between 60-70% when the clutch pedal is unaffected and 10-20% when the pedal is fully depressed.
The fault is intermittent at the moment if the values are OK.
Continue - Checking components and wiring
-------------------------------------------------
Checking components and wiring
- Ignition off
- Check the resistance of the clutch pedal sensor between terminals #2 and #4 (component side).
Check the clutch pedal sensor and engine control module (ECM) connectors. Check for contact resistance and oxidation.
Check the signal cable between engine control module (ECM) terminal #B15 (#B25) and clutch pedal sensor terminal #2 (component side). Check for an open-circuit. Check for a short-circuit to supply voltage.
Check the signal ground cable between engine control module (ECM) terminal #B4 (#B14) and clutch pedal sensor terminal #4 (wiring side). Check for an open-circuit.
Hint: With the ignition on, the power supply to the clutch pedal sensor must be approximately 5 V (measured with the clutch pedal sensor disconnected), measured between terminals #2 and #4 (wiring side).
Remedy as necessary

Hint: After carrying out the repair, check that the fault has been remedied.
- Ignition off
- Reconnect the connectors, reinstall components etc.
- Ignition on
- Read off the clutch pedal movement by carefully pressing and releasing the clutch pedal.
Check that the value changes with clutch pedal movement. The value must be between 60-70 % when the clutch pedal is unaffected and 10-20% when the pedal is fully depressed.
The fault has been remedied if the values are OK.
