P0CC9Charge Port Door A Open Request Switch Circuit Low
- Generic OBD-II code · Powertrain
- Turns on the check-engine light
- Needs a drive cycle to confirm a fix
- How the car detects it
- 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.
