P08A7Clutch Pedal Position Sensor A Circuit/Open
- Generic OBD-II code · Powertrain
- Turns on the check-engine light
- Matters for the ITP
- How the car detects it
- 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.
- What you may notice
- Malfunction indicator lamp on
- Start-stop and cruise control unavailable
- Engine may not crank if the starter release relies on the sensor
- Likely causes
- 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
- RareFaulty sensor input in the engine control module
- Inspection (ITP)
- Matters for the ITP. While the check-engine light is on, the car fails the emissions check.
- Repair
- Easy · Often possible to do yourself.Typical cost: €50 – €300
