Faulty Signal

Faulty signal

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.

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 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.
Check the clutch pedal sensor installation. Search for damage and check the connections visually.

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.
