Clutch Position Sensor Performance Problem
The clutch position sensor is not sending the correct signal to the engine control module (ECM).
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 clutch position sensor tells the computer when the clutch is pressed or released. If it’s not working right, the car can act weird, like not shifting properly or stalling.
What the computer is actually seeing
The ECM expects a voltage signal between 0.5V (clutch released) to 4.5V (clutch pressed). If it sees anything outside that range or no signal, it sets this code.
What a healthy reading looks like
0.5V to 4.5V depending on clutch position, ideally a smooth transition as the clutch is engaged and disengaged.
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.
- 1Inspect wiring and connectors to the clutch position sensor for damage or corrosion. Decision Point: If damaged, repair/replace wiring; if OK, proceed to next step.
- 2Using a multimeter, check the voltage output of the clutch position sensor with the clutch in both positions. Decision Point: If not between 0.5V and 4.5V, replace the sensor; if within range, proceed to next step.
- 3Clear the code and test drive the vehicle to see if the code returns. Decision Point: If the code does not return, the issue was intermittent; if it returns, consider replacing the ECM.
Common causes
- Faulty clutch position sensor
- Damaged wiring or connectors
- Dirty or contaminated sensor contacts
- Clutch misalignment or mechanical failure

Frequently asked questions
Is it safe to drive with this code?
It's drivable but may affect shifting performance. Address it soon to avoid further issues.
Will this code come back after clearing it?
It may return if the underlying problem isn't fixed, so further diagnostics is often needed.
Why might this code pair with P0811 or P0812?
These codes also deal with clutch position sensors and can indicate similar or related issues.
