What P0806 means
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.
P0806 at a glance
- Check engine lightYes, usually on
- Emissions testCan fail
- Limp modePossible
- Repair difficultyMedium
- Typical labor0.5 to 3 hours
- Clears after repairWhen cleared with a scanner
Symptoms of P0806
- 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
Common causes of P0806
- Most 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)
- Less likelyMaster cylinder leaking, pedal does not fully return
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of P0806 means
| P | Powertrain system: engine, fuel system, ignition, emissions and transmission. |
| 0 | Generic code: it means the same on every make (SAE standard). |
| 8 | Area: transmission. |
| 06 | The exact fault in that area. |
What to do next
- Note P0806 and any other codes stored with it: several codes together often point to one cause.
- Check for loose connectors and damaged wiring around the parts the code names.
- Check open recalls for your car: some faults are fixed for free by the dealer. Enter your VIN.
- Clear the code only after the repair. If it comes back, the fault is still there.
Buying a used car? Scan it for stored codes before you pay. A recently cleared memory can hide a problem.
Questions about P0806
What does P0806 mean?
P0806 means "Clutch Position Sensor A Circuit Range/Performance". The 'Clutch Position Sensor A' family (P0805 circuit to P0809, P080A not learned) means different parts by vehicle generation. It is a generic code, so it means the same on every make.
Is it safe to drive with P0806?
Drive gently and only to a workshop. With P0806 the car can go into limp mode (reduced power) to protect itself.
Will P0806 fail an emissions test?
Yes, it can. P0806 is emissions-related, so most inspection programs fail a car while it is stored or while the check engine light is on.
How hard is P0806 to fix?
Difficulty: medium. A typical repair takes 0.5 to 3 hours of work. This is a job for a workshop.
Will P0806 clear itself after the repair?
Clear the code with a scanner after the repair. If the fault is fixed, it does not come back.
