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.

Likely causes

Loose connector or broken wire at the pedal sensor (pedal box wiring flexes with every clutch stroke)
Internal fault in clutch pedal position sensor A
Missing 5 V reference or sensor ground
Faulty sensor input in the engine control module

Symptoms

  • Malfunction indicator lamp on
  • Start-stop and cruise control unavailable
  • Engine may not crank if the starter release relies on the sensor
