P2E93 Charge Port Door B Open Request Switch Circuit

P2E93 is the basic circuit fault of the input with which the driver asks the second charge flap to open. On cars with a flap on each side this input is usually a touch or wipe sensor on the flap itself: Porsche's Taycan and Cayenne Electric open each flap when a hand passes over a sensor area at its rear, and Porsche's WLK2 parts list calls the passenger-side flap door B. No manufacturer documents P2E93 publicly. GM shows how the A version P0CC7 works on the 2011 Volt: a reading in the forbidden band from 65.9 to 81.6 percent of reference, seen in six of eight 50 ms samples, sets a Type B code. Low and high faults belong to P2E95 and P2E96, implausible behaviour to P2E94. Typically flap B ignores the hand but still opens from the screen.

Likely causes

Touch or wipe sensor of flap B with a wrong internal resistance
Partly broken or corroded signal wire to the flap B sensor
Moisture in the connector at the flap module
Faulty input stage in the control unit reading the sensor

Symptoms

  • Charge flap B does not react to touch or hand gesture
  • Flap B still opens via the central display or app
  • Charging flap warning in the instrument cluster
