P0806Clutch Position Sensor A Circuit Range/Performance
- Generic OBD-II code · Powertrain
- Turns on the check-engine light
- Matters for the ITP
- Can trigger limp mode
- How the car detects it
- The 'Clutch Position Sensor A' family (P0805 circuit to P0809, P080A not learned) means different parts by vehicle generation. GM used P0806–P080A until model year 2018 for the analog clutch pedal sensor of its manual cars, then the newer pedal sensor codes P08A8 ff; Saab's 2012 9-3 does the same. Ford's DPS6 dual clutch uses the family for the electric motor of clutch A. P0806 is the plausibility check. On GM's LT4 manual cars the pedal sensor is compared with gear detection: if it reports the clutch pressed while engine and output speed show a valid gear, a filtered position error above 4 % sets the code (above 5.6 mph, not in 4WD low), type A with the MIL after one trip. On Ford's DPS6 it reports a fault of the Hall sensors on the clutch A motor; Saab sets it for a frozen pedal signal and switches off cruise control.
- What you may notice
- Check engine lamp on
- Cruise control and start-stop not working
- Engine starts only with the pedal fully pressed, or not at all
- Dual clutch: jerky take-off, limp mode
- Likely causes
- LikelyPedal sensor or Hall sensors of the clutch motor faulty
- PossiblePedal sensor misadjusted or not relearned after clutch work
- PossibleHarness or connector with contact resistance
- PossibleClutch actuator motor faulty (DPS6)
- RareMaster cylinder leaking, pedal does not fully return
- Inspection (ITP)
- Matters for the ITP. While the check-engine light is on, the car fails the emissions check.
