Clutch Pedal Position Sensor Circuit

Diagnostic & Technical Explanation
Code P08A7 (Clutch Pedal Position Sensor A Circuit/Open) sets when the TCM sees an open, shorted, or implausible analog signal from a clutch pedal position sensor on an automated manual or dual-clutch transmission, or the sensor's zero-point has not been learned. Unlike a simple on/off clutch switch, this potentiometer/Hall sensor reports continuous pedal travel used to blend clutch engagement, so causes are sensor wear, a lost calibration after service, or chafed wiring at the pedal bracket.

These 13 diagnostic trouble codes share one detection mechanism and one repair path, which is why MechanicDB groups them into a single authored fault family rather than repeating the same explanation 13 times.
