What does code P08AA mean?

Q: What does code P08AA mean?

Clutch Pedal Position Sensor A Circuit High. P08AA indicates that the powertrain control module (PCM) has detected a high voltage condition on the signal circuit for clutch pedal position sensor A, which typically means the circuit is open, shorted to voltage, or the sensor's internal resistance has risen abnormally. The PCM expects the sensor's signal voltage to stay within a calibrated range as the clutch pedal moves, and a sustained high reading falls outside that range.
