Clutch Position Sensor Circuit Range/Performance Problem

The computer is having trouble figuring out how far the clutch pedal is pressed. This can cause shifting problems in manual transmissions.

The PCM expects a variable voltage signal from the clutch position sensor that indicates how far the pedal is pressed (0 to 5 volts). If it sees a voltage that’s either too low or too high beyond preset limits, it triggers the code.

Don't just throw parts at it. Walk through these in order — each step tells you whether to keep going or stop and fix what you found.

1. 11. Inspect the wiring and connectors at the clutch position sensor for damage or corrosion. Repair or replace if needed. Decision Point: Is the wiring intact? If yes, go to step 2. If no, repair/reconnect and recheck code.
2. 22. Measure the voltage at the clutch position sensor connector with the key on, engine off. Expected: 0V when the pedal is up and about 5V when the pedal is fully down. Decision Point: Are the voltages within range? If yes, go to step 3. If no, replace the clutch position sensor.
3. 33. Check for any mechanical binding or improper adjustment in the clutch linkage. Ensure smooth operation. Decision Point: Is the clutch operating smoothly? If yes, further diagnose ECU issues. If no, adjust or repair the clutch mechanism.

• Faulty clutch position sensor
• Wiring issues or corrosion in connector
• Improperly adjusted clutch mechanism
• Faulty PCM (rare)
