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.
Medium severity. Can I keep driving?Drive gently to a repair shop. If it slips, you hear clunks, or it loses its gears, do not keep driving.
Symptoms
- 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
Most likely causes
- Pedal sensor or Hall sensors of the clutch motor faulty
- Pedal sensor misadjusted or not relearned after clutch work
- Harness or connector with contact resistance
- Clutch actuator motor faulty (DPS6)
- Master cylinder leaking, pedal does not fully return
What to check, in order
Start with the simplest. You can tick off each step.
Good to know
- Repair difficulty: medium
- It can trigger limp mode.
- It affects emissions.
What each character of P0806 means
- P: Powertrain: engine and transmission
- 0: Generic code: same on every make
- 8: Transmission
- 06: Specific fault in that system
Frequently asked questions
Can I keep driving with code P0806?
Drive gently to a repair shop. If it slips, you hear clunks, or it loses its gears, do not keep driving.
What causes code P0806?
The most common causes are: pedal sensor or Hall sensors of the clutch motor faulty; pedal sensor misadjusted or not relearned after clutch work; harness or connector with contact resistance.
