P0CC8Charge Port Door A Open Request Switch Circuit Performance
- Generic OBD-II code · Powertrain
- How the car detects it
- P0CC8 covers a plausibility fault of the charge flap A open request switch: the signal is electrically within limits, yet its behaviour makes no sense, for example a button that reports pressed for far too long or never changes state over many wake-ups. No manufacturer documents this code publicly. GM's Volt tables of 2011 to 2013 monitor the same switch only for invalid range, low and high (P0CC7, P0CC9, P0CCA), so the performance check is not used there. CARB 13 CCR 1968.2 (e)(15) requires rationality checks only for inputs that affect emissions or serve another diagnostic, which explains why such comfort inputs are often left out. A GM patent shows the typical layout, in which the release button makes the controller energize the flap actuator. Expect a flap that reacts erratically to the button.
