What P2E98 means
P2E98 is the general circuit code for the sensor that reports whether charge flap B is open or shut. Mercedes-Benz documents it: in its plug-in hybrids the separate DC charging socket has its own flap, and information LI47.70-P-078563 lists P2E9873 for a supposed electrical fault of that flap's position sensor, stored in the DC charge-connection unit N116/5 and the powertrain controller, with the MIL lit and the note that the actuator does not open. Starting and charging stay normal; the cause is software, the fix a DCCU update plus SCN coding, after which the code no longer lights the MIL, and parts must not be replaced. Porsche's Taycan detects flap end positions with a reed sensor. Low, high and erratic faults are P2E9A, P2E9B and P2E9C, plausibility P2E99.
P2E98 at a glance
- Check engine lightYes, usually on
- Emissions testNot an emissions code
- Limp modeNot expected
- Repair difficultyWorkshop only
- Typical labor0.5 to 2 hours
- Clears after repairWhen cleared with a scanner
Symptoms of P2E98
- Malfunction indicator lamp on, charging and starting normal (Mercedes)
- Flap B may stay shut or show a wrong status
Common causes of P2E98
- Most likelySoftware fault in the DC charging unit reporting a false sensor fault (Mercedes)
- PossiblePosition sensor of flap B with a wrong internal resistance
- PossibleDamaged wire or connector between sensor and control unit
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of P2E98 means
| P | Powertrain system: engine, fuel system, ignition, emissions and transmission. |
| 2 | Generic code (second SAE range): it means the same on every make. |
| 98 | The exact fault in that area. |
What to do next
- Note P2E98 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 P2E98
What does P2E98 mean?
P2E98 means "Charge Port Door B Position Sensor Circuit". P2E98 is the general circuit code for the sensor that reports whether charge flap B is open or shut. It is a generic code, so it means the same on every make.
Is it safe to drive with P2E98?
Usually yes, for a short time, if the check engine light is steady and the car drives normally. If the light flashes or the car runs badly, stop and have it checked.
Will P2E98 fail an emissions test?
P2E98 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 P2E98 to fix?
Difficulty: workshop only. A typical repair takes 0.5 to 2 hours of work. This is a job for a workshop.
Will P2E98 clear itself after the repair?
Clear the code with a scanner after the repair. If the fault is fixed, it does not come back.
