P2E9ACharge Port Door B Position Sensor Circuit Low

  • Generic OBD-II code · Powertrain
How the car detects it
P2E9A reports that the flap B position signal has fallen under its lowest valid value. A signal wire chafed against ground, water in the connector or an internally shorted sensor are the usual reasons. Tesla's latch patent shows a common build in which a reed or Hall element inside the latch senses a magnet disc on the door, so the signal follows the gap between them. No manufacturer documents P2E9A publicly. For the A flap of the 2011 Volt, GM sets P0CCE as Type B when 6 out of 8 readings fall under 22.9 percent, and while a position code is active it holds back the control pilot test P0CF4 and the opening check P0CD2. P2E9B is the high counterpart, P2E98 the general circuit code. Expect a flap state that never changes and possibly blocked charging.
