P2E96 is stored when the request signal of charge flap B climbs past the top of its permitted range. Contact with a 12 V supply raises it, and so does a broken sensor ground or switch path that lets a pulled-up input float. The control unit then usually sees a request that never arrives. No manufacturer documents P2E96 publicly. GM's Volt table for flap A sets the matching P0CCA when readings pass 94.5 percent in 6 out of 8 cases, Type B. On Porsche's Taycan each flap can be moved both from the centre console and by the touch-free sensor; bulletin 186/24 has technicians test both ways on both sides and check lines and plug connections before replacing parts. Low readings are P2E95, the invalid middle band P2E93.

Likely causes

Sensor signal wire shorted to a 12 V supply
Interrupted ground or switch path at the flap B sensor
Pushed-back or loose pin in the flap module connector

Symptoms

  • Flap B never reacts to the hand or touch
  • Opening from the centre console or display still works
  • Warning that the charging flap is impaired
