P2E9DCharge Port Door B Unlock Control Circuit

  • Generic OBD-II code · Powertrain
How the car detects it
P2E9D concerns the output that releases or drives charge flap B, not its sensors. Depending on the design this is a latch actuator or a small motor: Audi's e-tron family uses lock actuators F496 and F497 for its high-voltage charging flaps on the two sides, and Porsche's Taycan a servo motor per charge port door. No manufacturer documents P2E9D publicly. GM's 2011 Volt shows how the A version P0CD1 is judged from the fault flag of the driver stage: a short to ground while the release is commanded (3 of 4 samples), a short to 12 V or an open circuit while it is not (64 of 80 samples, 50 ms each), Type B. Split low and high codes are P2E9F and P2EA0, the movement check P2E9E. The driver finds flap B shut and has to use the other side or the emergency release.
