P2E98Charge Port Door B Position Sensor Circuit
- Generic OBD-II code · Powertrain
- Turns on the check-engine light
- How the car detects it
- 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.
