Clutch Position Sensor Circuit Range/Performance
The P0806 code means the vehicle's onboard diagnostic system has detected: Clutch Position Sensor Circuit Range/Performance. This is a moderate severity code.
- Keep driving?
- Short distances only
- DIY difficulty
- moderate
- Estimated cost
- $50 - $350 (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.

Common Symptoms
- Check Engine Light illuminated
- Cruise control inoperative
- Intermittent no-start condition
- Engine may stall when clutch is released slowly
Probable Causes (Ranked by Likelihood)
- Worn or misadjusted clutch position sensor Very High
- Clutch pedal freeplay out of specification High
- Intermittent wiring fault in sensor circuit Moderate
- Worn clutch pedal bushings causing erratic sensor readings Low
Step-by-Step Diagnostic Procedure
-
Monitor clutch position sensor data with a scan tool while slowly pressing the pedal
-
Check for smooth, linear voltage change across the full pedal range
-
Inspect clutch pedal bushings and pivot points for excessive wear
-
Verify clutch pedal freeplay is within manufacturer specifications
Frequently Asked Questions
What does range/performance mean for P0806?
It means the clutch position sensor is sending a signal that is within the valid voltage range but does not match expected behavior. The sensor may be reading inconsistently or not changing smoothly.
Can worn clutch pedal bushings cause P0806?
Yes, worn bushings allow the pedal to wobble, which causes the sensor to produce erratic readings even though the sensor itself is functioning.
Is P0806 different from P0805?
Yes. P0805 indicates a complete circuit malfunction (no signal), while P0806 indicates the signal is present but not within the expected performance range.
