- How the car detects it
- P0CCE reports that the charge flap A position sensor signal has fallen below its lowest valid level, the classic sign of a signal wire shorted to ground or a sensor that has failed short. GM documents it for the 2011 to 2013 Chevrolet Volt: the hybrid control module 2 sets it when the reading is under 22.9 percent of reference in six of eight samples, and as a Type B code the lamp comes on after two trips. While it is active, GM suspends dependent tests such as the control pilot check P0CF4 and the flap opening check P0CD2. The high-side counterpart is P0CCF, the invalid middle window P0CCC. For the driver this mostly means a wrong flap status in the display and, depending on software, blocked charging.
