P0CCB code meaning
Charge Port Door A Open Request Switch Circuit Intermittent/Erratic
What P0CCB means
P0CCB flags a charge flap A open request switch whose signal jumps between states without a matching press, or drops out briefly. Such signals usually come from loose terminals, a cracked solder joint in the switch or a harness that flexes with a door or body panel. No manufacturer documents this code publicly; GM's Volt tables of 2011 and 2012 cover the same switch only with P0CC7, P0CC9 and P0CCA, which use six of eight samples as a filter and would hide short dropouts. CARB 13 CCR 1968.2 (e)(15) makes intermittent checks mandatory only for emission-related inputs, so a comfort switch like this one rarely carries one. The GM charge port patent shows how the button press leads the controller to fire the flap actuator. The driver sees the flap answer only now and then.
P0CCB at a glance
- Check engine lightUsually not
- Emissions testNot an emissions code
- Limp modeNot expected
- Repair difficultyMedium, DIY possible
- Typical labor0.5 to 2.5 hours
- Clears after repairWhen cleared with a scanner
Symptoms of P0CCB
- Charge flap opens only occasionally when the button is pressed
- Fault comes and goes, often with temperature or road vibration
Common causes of P0CCB
- Most likelyLoose or spread terminal at the switch or module connector
- PossibleCracked solder joint or worn contact inside the switch
- PossibleHarness damaged where it flexes with a door or panel
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of P0CCB 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. |
| CB | The exact fault in that area. |
What to do next
- Note P0CCB 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 P0CCB
What does P0CCB mean?
P0CCB means "Charge Port Door A Open Request Switch Circuit Intermittent/Erratic". P0CCB flags a charge flap A open request switch whose signal jumps between states without a matching press, or drops out briefly. It is a generic code, so it means the same on every make.
Is it safe to drive with P0CCB?
P0CCB does not normally turn on the check engine light by itself. Watch for the symptoms above and have it checked soon.
Will P0CCB fail an emissions test?
P0CCB 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 P0CCB 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 P0CCB clear itself after the repair?
Clear the code with a scanner after the repair. If the fault is fixed, it does not come back.
