What P0CCE means
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.
P0CCE 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 P0CCE
- Wrong flap status in the display
- Warning lamp after two trips (GM Volt)
- Charging may be refused
Common causes of P0CCE
- Most likelySensor signal wire shorted to ground
- PossiblePosition sensor shorted internally
- PossibleWater in the flap area or sensor connector
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of P0CCE 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. |
| CE | The exact fault in that area. |
What to do next
- Note P0CCE 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 P0CCE
What does P0CCE mean?
P0CCE means "Charge Port Door A Position Sensor Circuit Low". 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. It is a generic code, so it means the same on every make.
Is it safe to drive with P0CCE?
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 P0CCE fail an emissions test?
P0CCE 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 P0CCE 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 P0CCE 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.
