P0CCCCharge Port Door A Position Sensor Circuit
- Generic OBD-II code · Powertrain
- Turns on the check-engine light
- Needs a drive cycle to confirm a fix
- How the car detects it
- The position sensor of charge flap A tells the vehicle whether the flap is open or shut; GM has patented a version in which a magnet on the flap acts on a magnetic sensor in the housing. P0CCC is the general circuit code for this sensor. On the 2011 to 2013 Chevrolet Volt it sets when the reading lands in the invalid window of 65.9 to 81.6 percent of reference in six of eight samples, as a Type B code with the lamp after two trips. GM uses the flap state as an enable condition for the control pilot check P0CF4, which is why the sensor is part of the OBD system there; GM's 2016 hybrid table no longer lists these flap codes. Short circuits have their own codes, P0CCE (low) and P0CCF (high). The driver may see a false flap-open message or a charging refusal.
