Clutch Position Sensor Circuit Failure
The clutch position sensor is malfunctioning or not communicating properly.
Heads up: this code wasn't in our hand-written library yet, so DiagCoach AI built this page on the fly. Double-check critical specs against service info before condemning parts.
What it means (plain English)
The computer expects to see a certain voltage from the clutch position sensor when the clutch pedal is pressed or released, but it isn't getting that signal. This usually means the sensor is broken or there's a wiring issue.
What the computer is actually seeing
The control module expects to receive a voltage signal indicating the position of the clutch pedal, typically within a range of 0.5 to 4.5 volts, depending on the pedal position. If the voltage is outside this range or missing, the code triggers.
What a healthy reading looks like
Normal operation should show 0.5V with the clutch released and 4.5V with the clutch fully engaged.
Guided diagnostic — the DiagCoach way
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.
- 11. Inspect the wiring and connector of the clutch position sensor for damage or corrosion. Repair or replace as necessary. Decision: If you find issues here, fix them and retest. If not, proceed to step 2.
- 22. Disconnect the sensor and check for voltage at the harness connector. With the ignition on, expect to see around 5V supply voltage. Decision: If voltage is present, the sensor is likely faulty. If not, check the wiring back to the control module.
- 33. Replace the clutch position sensor if it was determined faulty. Clear the code and test drive the vehicle.
- 44. If the code returns, check for any other related faults in the control module or issues in the wiring. This may indicate further electrical problems.
Common causes
- Faulty clutch position sensor
- Damaged wiring or connectors
- Corrosion at the electrical connector
- Incorrect installation or adjustment of the sensor

Frequently asked questions
Is it safe to drive with this code?
It's generally safe to drive, but you may experience shifting issues. Fix it soon.
Will the code come back?
If the underlying issue isn't fixed, yes, it will likely return.
Why does this code show with SPN 3308?
SPN 3308 is often related to the same clutch system. If there's an overarching problem, both codes can appear.
