What P08A7 means
Sensor A is the analog or PWM sensor that reports how far the clutch pedal of a manual car is pressed; the engine controller needs it for start-stop, cruise control, gear detection and starter release. P08A7 is the general circuit or open-wire fault of that sensor. No manufacturer documents this code publicly: GM folds an open circuit into its low-signal code P08A9, and Ford lists only P08A9/P08AA for sensor A. Saab's 2012 9-3 used the older P0806 as a comparable circuit fault (Check Engine, cruise control off). Range/performance, low, high and erratic faults have their own codes P08A8–P08AB. Expect a warning lamp and disabled start-stop or cruise control until the wiring or sensor is repaired.
P08A7 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 P08A7
- Malfunction indicator lamp on
- Start-stop and cruise control unavailable
- Engine may not crank if the starter release relies on the sensor
Common causes of P08A7
- Most likelyLoose connector or broken wire at the pedal sensor (pedal box wiring flexes with every clutch stroke)
- PossibleInternal fault in clutch pedal position sensor A
- PossibleMissing 5 V reference or sensor ground
- Less likelyFaulty sensor input in the engine control module
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of P08A7 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. |
| A7 | The exact fault in that area. |
What to do next
- Note P08A7 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 P08A7
What does P08A7 mean?
P08A7 means "Clutch Pedal Position Sensor A Circuit/Open". Sensor A is the analog or PWM sensor that reports how far the clutch pedal of a manual car is pressed; the engine controller needs it for start-stop, cruise control, gear detection and starter release. It is a generic code, so it means the same on every make.
Is it safe to drive with P08A7?
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 P08A7 fail an emissions test?
Yes, it can. P08A7 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 P08A7 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 P08A7 clear itself after the repair?
Clear the code with a scanner after the repair. If the fault is fixed, it does not come back.
