P2E92 code meaning
Charge Port Door B Open Request Switch Wake-Up Circuit
What P2E92 means
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.
P2E92 at a glance
- Check engine lightUsually not
- Emissions testNot an emissions code
- Limp modeNot expected
- Repair difficultyMedium
- Typical labor0.5 to 2.5 hours
- Clears after repairWhen cleared with a scanner
Symptoms of P2E92
- Charge door B does not open on request every time
- Door opens only from the screen or the other side works normally
- Increased standby drain if the line keeps waking modules
Common causes of P2E92
- Most likelyOpen or shorted wake-up wire between switch and control unit
- PossibleWorn switch or sensor at door B giving mismatched signals
- PossibleWater ingress or corrosion at the door B connector
- Less likelyWake-up input of the control unit faulty
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of P2E92 means

| 2 | Generic code (second SAE range): it means the same on every make. |
| 92 | The exact fault in that area. |
What to do next
- Note P2E92 and any other codes stored with it: several codes together often point to one cause.
- Check for loose connectors and damaged wiring around the parts the code names.
- Check open recalls for your car: some faults are fixed for free by the dealer. Enter your VIN.
- Clear the code only after the repair. If it comes back, the fault is still there.
Buying a used car? Scan it for stored codes before you pay. A recently cleared memory can hide a problem.
