What P0CCA means
With P0CCA the control module sees the charge flap A open request switch signal above its highest valid level. Depending on the circuit, a wire shorted to battery voltage or an interrupted ground or switch path pushes the reading up. GM's Volt monitor from 2011 onward flags it when more than 94.5 percent of the reference is measured in six of eight samples, then stores it as a Type B code with the lamp after two trips; the 2013 table stretches the sample spacing to 500 ms. Low readings below 22.9 percent go to P0CC9 instead, and an invalid middle value to P0CC7. Since a high reading usually looks like a button that is never pressed, the typical complaint is a charge flap that cannot be opened from the switch.
P0CCA 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 P0CCA
- Charge flap cannot be opened with the button
- Warning lamp after two trips (GM Volt)
Common causes of P0CCA
- Most likelySignal wire shorted to a 12 V supply
- PossibleInterrupted ground or switch return path
- PossiblePin pushed back in the connector
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of P0CCA 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. |
| CA | The exact fault in that area. |
What to do next
- Note P0CCA 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 P0CCA
What does P0CCA mean?
P0CCA means "Charge Port Door A Open Request Switch Circuit High". With P0CCA the control module sees the charge flap A open request switch signal above its highest valid level. It is a generic code, so it means the same on every make.
Is it safe to drive with P0CCA?
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 P0CCA fail an emissions test?
P0CCA 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 P0CCA 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 P0CCA 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.
