What P0CC9 means
P0CC9 means the open request switch of charge flap A reads lower than any valid state, which typically results from the signal wire touching ground or from a switch that has failed short. In the Chevrolet Volt tables of 2011 to 2013, GM sets it once the reading drops under 22.9 percent of the reference in six of eight samples; the code is Type B, so the warning lamp follows after two consecutive trips. The monitor belongs to the hybrid control module 2 (VICM). The opposite fault, a reading above 94.5 percent, is P0CCA, and a value stuck between valid states is P0CC7. Because a grounded signal may look like a permanently pressed button, the flap can fail to respond or the module may stay awake longer than intended.
P0CC9 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 P0CC9
- Charge flap does not react to the button
- Warning lamp after two trips (GM Volt)
Common causes of P0CC9
- Most likelySignal wire chafed through to body ground
- PossibleOpen request switch shorted internally
- PossibleWater in the switch connector creating a leakage path to ground
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of P0CC9 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. |
| C9 | The exact fault in that area. |
What to do next
- Note P0CC9 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 P0CC9
What does P0CC9 mean?
P0CC9 means "Charge Port Door A Open Request Switch Circuit Low". P0CC9 means the open request switch of charge flap A reads lower than any valid state, which typically results from the signal wire touching ground or from a switch that has failed short. It is a generic code, so it means the same on every make.
Is it safe to drive with P0CC9?
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 P0CC9 fail an emissions test?
P0CC9 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 P0CC9 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 P0CC9 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.
