P2E92Charge Port Door B Open Request Switch Wake-Up Circuit
- Generic OBD-II code · Powertrain
- How the car detects it
- P2E92 concerns cars with a second electrically opened charge door. Its open-request switch or sensor must be able to rouse sleeping control units, so besides its normal signal it drives a wake-up line, and P2E92 records that the two disagree. Porsche's Taycan campaign WLK2 shows the naming, door A at the driver and door B at the passenger side, both opened by a hand gesture over a sensor; Audi's newer models put an extra AC inlet with its own flap on the opposite side, also opened at the flap. No manufacturer documents P2E92. GM's 2011 Volt tests the A version, P0CC6: wake-up active with the switch released, or pressed without wake-up, filtered in 50 ms steps, Type B over two trips. The usual result is a door B that sometimes ignores a press.
