P2EA0Charge Port Door B Unlock Control Circuit High
- Generic OBD-II code · Powertrain
- How the car detects it
- P2EA0 marks the opposite case at the flap B release output: the line sits at a high voltage while the driver stage should be pulling it down or keeping it off. Contact with a 12 V circuit does this, and on low-side switched outputs an interrupted actuator or wire gives the same reading. No manufacturer documents P2EA0 publicly. GM's Volt checks the A output for a short to battery or an open line only while no release is commanded, needing 64 of 80 samples at 50 ms, and reports it within P0CD1. Tesla's latch patent explains why a permanently powered release is unwanted: the electromagnet is fed only briefly through a normally open switch to cancel the holding magnet. Audi's e-tron campaign 93H6 shows the fallback when a flap stays shut, the manual release. Low-level faults are P2E9F, the movement check P2E9E.

- Likely causes
- LikelyControl wire of the flap B actuator shorted to 12 V
- PossibleOpen actuator winding or broken wire on a low-side driven output
- RareOutput stage in the control unit stuck on
