Clutch Position Sensor Circuit High
The P0808 code means the vehicle's onboard diagnostic system has detected: Clutch Position Sensor Circuit High. This is a moderate severity code.
- Keep driving?
- Short distances only
- DIY difficulty
- moderate
- Estimated cost
- $40 - $300 (parts and labor)
Read and clear transmission codes. Many trans codes are caused by low or burnt fluid -- check level and color before assuming the worst.
Basic scanners only read engine codes. This reads transmission, ABS, and airbag too.

What Are the Symptoms of P0808?
- Check Engine Light illuminated
- Cruise control inoperative
- PCM reads clutch as always engaged
- Possible no-start condition
What Causes P0808? (Most Likely First)
- Open circuit in clutch position sensor ground wire Very High
- Faulty clutch position sensor stuck high High
- Short to voltage in the sensor signal wire Moderate
- PCM reference voltage issue Low
Can I Still Drive with P0808?
Short distances only. P0808 is rated moderate severity. Keep trips short and get it diagnosed soon rather than waiting for symptoms to worsen.
Frequently Asked Questions
What does high input mean for the clutch sensor?
High input means the voltage on the signal wire is above the expected maximum. This is often caused by an open ground or a short to the voltage supply.
Can I test the clutch position sensor with a multimeter?
Yes. With the sensor connected, backprobe the signal wire and check for voltage change as you press and release the clutch. If it stays high, the sensor or wiring is faulty.
Is P0808 the opposite of P0807?
Yes. P0807 indicates the signal is too low while P0808 indicates it is too high. Both point to issues with the clutch position sensor circuit.

How Do You Diagnose P0808?
-
Measure voltage at the clutch position sensor with key on, engine off
-
Check for an open ground wire at the sensor connector
-
Look for a short to battery voltage in the signal wire
-
Test sensor operation by monitoring live data while pressing the clutch pedal
