P2E9CCharge Port Door B Position Sensor Circuit Intermittent/Erratic
- Generic OBD-II code · Powertrain
- How the car detects it
- P2E9C covers a flap B position signal that flickers or drops out briefly instead of failing for good. Common sources are loose terminals, a harness bent at every flap movement, or a sensor sitting loose in its holder. No manufacturer documents P2E9C publicly. Two official cases show how fragile this signal path can be on two-flap cars. Porsche replaced the harnesses of flap A on the driver side and flap B on the passenger side of 2020 Taycans because an incorrect sensor signal made the car misread the end position. Audi traced wrongly shown flap states on the e-tron GT to the actuator, naming oxidation and foreign particles inside it. Lasting faults are P2E98, P2E9A and P2E9B, plausibility errors P2E99. Drivers see a flap status that changes on its own or charging warnings that come and go.
