P2E99Charge Port Door B Position Sensor Circuit Performance

  • Generic OBD-II code · Powertrain
How the car detects it
P2E99 means the position signal of charge flap B is within its electrical limits yet contradicts what the flap is doing, for instance closed although the flap was just opened. On cars with two flaps such an error has side effects, because the flaps lock each other: Porsche found on the 2020 Taycan that a bad sensor signal led to a wrong end-position decision, which then blocked the flap on the other side, and replaced both flap harnesses (campaign WLK2); a GM patent describes the same interlock with a magnet sensor per door. Audi reports two e-tron GT cases where a closed flap was read as open: a faulty actuator with oxidation or particles (2064953/4) and, later, cockpit software (2079475/1). No manufacturer ties these to P2E99 publicly. Pure circuit faults belong to P2E98, P2E9A and P2E9B.
What you may notice
  • Message asking to close a charging flap although both are closed
  • Opposite flap A locked and not operable
  • Charging refused
Likely causes
  • LikelyPosition sensor or its harness giving a wrong end-position signal
  • PossibleOxidation or particles in the flap actuator that houses the detection
  • PossibleSoftware misreading the flap state at start-up
