What P0CCC means
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.
P0CCC at a glance
- Check engine lightYes, usually on
- Emissions testNot an emissions code
- Limp modeNot expected
- Repair difficultyMedium, DIY possible
- Typical labor0.5 to 2.5 hours
- Clears after repairAfter a drive cycle
Symptoms of P0CCC
- Flap-open message although the flap is closed
- Warning lamp after two trips (GM Volt)
- Charging or charge pilot checks may be blocked
Common causes of P0CCC
- Most likelyFaulty flap position sensor or switch
- PossibleSensor or its harness pigtail not fully seated in the housing
- PossibleDamaged wire or corroded connector in the sensor circuit
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of P0CCC means
| P | Powertrain system: engine, fuel system, ignition, emissions and transmission. |
| 0 | Generic code: it means the same on every make (SAE standard). |
| C | Area: hybrid propulsion. |
| CC | The exact fault in that area. |
What to do next
- Note P0CCC and any other codes stored with it: several codes together often point to one cause.
- Check for loose connectors and damaged wiring around the parts the code names.
- Check open recalls for your car: some faults are fixed for free by the dealer. Enter your VIN.
- Clear the code only after the repair. If it comes back, the fault is still there.
Buying a used car? Scan it for stored codes before you pay. A recently cleared memory can hide a problem.
Questions about P0CCC
What does P0CCC mean?
P0CCC means "Charge Port Door A Position Sensor Circuit". 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. It is a generic code, so it means the same on every make.
Is it safe to drive with P0CCC?
Usually yes, for a short time, if the check engine light is steady and the car drives normally. If the light flashes or the car runs badly, stop and have it checked.
Will P0CCC fail an emissions test?
P0CCC is not an emissions code, so on its own it usually does not fail an emissions test. Other stored codes or a lit check engine light still can.
How hard is P0CCC to fix?
Difficulty: medium. A typical repair takes 0.5 to 2.5 hours of work. A careful DIY repair is possible with basic tools and a scanner.
Will P0CCC clear itself after the repair?
After the repair the car has to complete a drive cycle (a mix of city and highway driving) before the test runs again. Until then the readiness monitor shows "not ready", which can fail an inspection.
