What P0CC7 means
P0CC7 is the general circuit fault of the button that requests opening of charge flap A. GM reads this switch as a percentage of its reference and expects defined states; on the 2011 to 2013 Chevrolet Volt the code sets when the reading sits in a forbidden band between 65.9 and 81.6 percent, which indicates a wrong resistance, for instance a damaged switch or a partly broken wire. Six bad readings out of eight (50 ms steps in 2011/2012, 500 ms in the 2013 table) trigger it, and it is a Type B code with the lamp after two trips. Hard shorts are split off into P0CC9 (to ground) and P0CCA (to battery voltage); unstable signals belong to P0CCB. In daily use the flap may ignore the button, while opening via the key or screen can still work.
P0CC7 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 hours
- Clears after repairAfter a drive cycle
Symptoms of P0CC7
- Charge flap does not open with the button
- Warning lamp after two trips (GM Volt)
- Opening via key, app or screen still possible on some models
Common causes of P0CC7
- Most likelyOpen request switch with wrong internal resistance
- PossiblePartly broken wire or corroded connector raising circuit resistance
- PossibleMoisture in the switch housing
- Less likelyFaulty switch input in the control module
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of P0CC7 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. |
| C7 | The exact fault in that area. |
What to do next
- Note P0CC7 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 P0CC7
What does P0CC7 mean?
P0CC7 means "Charge Port Door A Open Request Switch Circuit". P0CC7 is the general circuit fault of the button that requests opening of charge flap A. It is a generic code, so it means the same on every make.
Is it safe to drive with P0CC7?
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 P0CC7 fail an emissions test?
P0CC7 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 P0CC7 to fix?
Difficulty: medium. A typical repair takes 0.5 to 2 hours of work. A careful DIY repair is possible with basic tools and a scanner.
Will P0CC7 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.
