Code P080A 2018 GMC Sierra Description

The Clutch Pedal Position (CPP) sensor is a three-wire sensor, connected to a 5 V reference circuit, a low reference circuit, and a signal circuit. The Engine Control Module (ECM) supplies 5 V to the CPP sensor and also provides a sensor ground path on the low reference circuit. The CPP sensor sends a voltage signal to the ECM on the signal circuit. The voltage on the signal circuit will vary from a voltage near 4 V when the clutch pedal is released, to a voltage near 1 V when the clutch pedal is applied. The Diagnostic Trouble Code (DTC) will be set if the CPP sensor learned apply position not learned.
