P0CCDCharge Port Door A Position Sensor Circuit Performance
- Generic OBD-II code · Powertrain
- How the car detects it
- P0CCD is set when the charge flap A position signal is electrically valid but does not fit what the flap should be doing, for example a state that disagrees with the last commanded movement. GM bulletin 25-NA-049 (March 2025) names the code for the Ultium models Cadillac Lyriq 2023 to 2025, Chevrolet Blazer EV and Equinox EV 2024 to 2025, and Cadillac Optiq and Escalade IQ 2025: drivers see a Service High Voltage message, the cause is attributed to software, and dealers are told to reflash the BECM (battery energy control module) through vehicle wide programming without replacing parts. Porsche describes a related hardware case for the Taycan, where a wrong end-position signal locked the opposite flap and new harnesses fixed it. Circuit faults proper are P0CCC, P0CCE and P0CCF.
