P0CC8 code meaning
Charge Port Door A Open Request Switch Circuit Performance
What P0CC8 means
P0CC8 covers a plausibility fault of the charge flap A open request switch: the signal is electrically within limits, yet its behaviour makes no sense, for example a button that reports pressed for far too long or never changes state over many wake-ups. No manufacturer documents this code publicly. GM's Volt tables of 2011 to 2013 monitor the same switch only for invalid range, low and high (P0CC7, P0CC9, P0CCA), so the performance check is not used there. CARB 13 CCR 1968.2 (e)(15) requires rationality checks only for inputs that affect emissions or serve another diagnostic, which explains why such comfort inputs are often left out. A GM patent shows the typical layout, in which the release button makes the controller energize the flap actuator. Expect a flap that reacts erratically to the button.
P0CC8 at a glance
- Check engine lightUsually not
- Emissions testNot an emissions code
- Limp modeNot expected
- Repair difficultyMedium, DIY possible
- Typical labor0.5 to 2 hours
- Clears after repairWhen cleared with a scanner
Symptoms of P0CC8
- Charge flap opens unexpectedly or ignores the button
- Message about the charge flap in the instrument cluster
Common causes of P0CC8
- Most likelyMechanically sticking or jammed open request switch
- PossibleWorn switch contact giving an implausible signal
- Less likelyWiring fault that keeps the signal in an unexpected state
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of P0CC8 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. |
| C8 | The exact fault in that area. |
What to do next
- Note P0CC8 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 P0CC8
What does P0CC8 mean?
P0CC8 means "Charge Port Door A Open Request Switch Circuit Performance". P0CC8 covers a plausibility fault of the charge flap A open request switch: the signal is electrically within limits, yet its behaviour makes no sense, for example a button that reports pressed for far too long or never changes state over many wake-ups. It is a generic code, so it means the same on every make.
Is it safe to drive with P0CC8?
P0CC8 does not normally turn on the check engine light by itself. Watch for the symptoms above and have it checked soon.
Will P0CC8 fail an emissions test?
P0CC8 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 P0CC8 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 P0CC8 clear itself after the repair?
Clear the code with a scanner after the repair. If the fault is fixed, it does not come back.
