Faulty Signal

Faulty signal

Checking the status




- Ignition on.
Check the signal from the clutch pedal sensor.
Click on the VCT2000 symbol to read off the voltage level.
Slowly depress and release the clutch. Note a change in the signal level.
The voltage level in the clutch pedal sensor must be between 0.15 and 4.75 volts.





Does the value change?

Yes - Verification

No - Checking the component and wiring

-------------------------------------------------

Checking the component and wiring
Check control module connector terminals (#G12, G21, G23) and clutch pedal sensor connectors. Check for contact resistance and oxidation. Check for damage carefully.
Check the clutch pedal sensor resistance.
Check the signal cable between central electronic module (CEM) terminal #G21 (#21) and clutch pedal sensor connector terminal #3. Check for an open-circuit. Check for a short-circuit to ground.
Check the signal cable between central electronic module (CEM) terminal #G23 (#23) and clutch pedal sensor connector terminal #2. Check for an open-circuit. Check for a short-circuit to ground.
Check the signal cable between central electronic module (CEM) terminal #G12 (#12) and clutch pedal sensor connector terminal #1. Check for an open-circuit. Check for a short-circuit to ground.
Try replacing the clutch pedal sensor if no fault is found in the wiring.
Remedy as necessary.
