P2E93 code meaning
Charge Port Door B Open Request Switch Circuit
What P2E93 means
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.
P2E93 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 P2E93
- 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
Common causes of P2E93
- Most likelyTouch or wipe sensor of flap B with a wrong internal resistance
- PossiblePartly broken or corroded signal wire to the flap B sensor
- PossibleMoisture in the connector at the flap module
- Less likelyFaulty input stage in the control unit reading the sensor
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of P2E93 means
| P | Powertrain system: engine, fuel system, ignition, emissions and transmission. |
| 2 | Generic code (second SAE range): it means the same on every make. |
| 93 | The exact fault in that area. |
What to do next
- Note P2E93 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.
Questions about P2E93
What does P2E93 mean?
P2E93 means "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. It is a generic code, so it means the same on every make.
Is it safe to drive with P2E93?
P2E93 does not normally turn on the check engine light by itself. Watch for the symptoms above and have it checked soon.
Will P2E93 fail an emissions test?
P2E93 is not an emissions code, so on its own it usually does not fail an emissions test. Other stored codes or a lit check engine light still can.
How hard is P2E93 to fix?
Difficulty: medium. A typical repair takes 0.5 to 2.5 hours of work. This is a job for a workshop.
Will P2E93 clear itself after the repair?
Clear the code with a scanner after the repair. If the fault is fixed, it does not come back.
