P2E9BCharge Port Door B Position Sensor Circuit High
- Generic OBD-II code · Powertrain
- How the car detects it
- P2E9B is the high-side position fault of charge flap B: the reading lies above anything a working sensor can deliver. A signal wire touching 12 V, or a missing sensor ground, letting the input drift upwards, are typical explanations. No manufacturer documents P2E9B publicly. GM's Volt tables show the A version P0CCF flagging readings over 94.5 percent of the reference once six of eight samples agree, spaced 50 ms in 2011 and 500 ms in the 2013 table, as a Type B code. In GM's magnet sensor patent the door signal mainly drives an open-door warning and the interlock between two doors, so a stuck reading tends to produce a permanent flap-open message. Low readings are P2E9A, implausible but valid ones P2E99. The driver typically cannot charge on either side until the fault is gone.
