P0CC7Charge Port Door A Open Request Switch Circuit

  • Generic OBD-II code · Powertrain
  • Turns on the check-engine light
  • Needs a drive cycle to confirm a fix
How the car detects it
P0CC7 is the general circuit fault of the button that requests opening of charge flap A. GM reads this switch as a percentage of its reference and expects defined states; on the 2011 to 2013 Chevrolet Volt the code sets when the reading sits in a forbidden band between 65.9 and 81.6 percent, which indicates a wrong resistance, for instance a damaged switch or a partly broken wire. Six bad readings out of eight (50 ms steps in 2011/2012, 500 ms in the 2013 table) trigger it, and it is a Type B code with the lamp after two trips. Hard shorts are split off into P0CC9 (to ground) and P0CCA (to battery voltage); unstable signals belong to P0CCB. In daily use the flap may ignore the button, while opening via the key or screen can still work.
