What P0808 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. P0808 means the signal is too high. GM sets it above 96 % of the 5 V reference with the same 200 of 250 samples of 12.5 ms, type A with the MIL after one trip; Saab's 2012 9-3 above 4.8 V for longer than 0.6 s, with cruise control switched off. Typical causes are an open sensor ground or a signal wire shorted to the 5 V reference or battery voltage.
P0808 at a glance
- Check engine lightYes, usually on
- Emissions testCan fail
- Limp modeNot expected
- Repair difficultyEasy, DIY possible
- Typical labor0.3 to 1.5 hours
- Clears after repairWhen cleared with a scanner
Symptoms of P0808
- Check engine lamp on
- Cruise control not working
- Start-stop disabled
Common causes of P0808
- Most likelySensor ground open
- PossibleSignal shorted to 5 V or battery voltage
- PossiblePedal sensor faulty
- Less likelyMoisture or corrosion in the connector
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of P0808 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. |
| 08 | The exact fault in that area. |
What to do next
- Note P0808 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 P0808
What does P0808 mean?
P0808 means "Clutch Position Sensor A Circuit High". 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 P0808?
Usually yes, for a short time, if the check engine light is steady and the car drives normally. If the light flashes or the car runs badly, stop and have it checked.
Will P0808 fail an emissions test?
Yes, it can. P0808 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 P0808 to fix?
Difficulty: easy. A typical repair takes 0.3 to 1.5 hours of work. A careful DIY repair is possible with basic tools and a scanner.
Will P0808 clear itself after the repair?
Clear the code with a scanner after the repair. If the fault is fixed, it does not come back.
