P0E5FBattery Charger Coupler Temperature A Too High
- Generic OBD-II code · Powertrain
- Turns on the check-engine light
- How the car detects it
- P0E5F is not a sensor fault: the coupler temperature sensor A works, but the charging inlet really got too hot. Three makers document it. Ford links it on the 2021–2023 Mustang Mach-E (stored in the SOBDM) to a red flashing charge indicator and no charging from a 48 A level 2 station, while 32 A or less may still work; SSM 51866 calls for a new charge port. GM's PIT5904 for the 2022 Hummer EV and BrightDrop EV600 says the pin temperatures are watched all the time and that, once the code has tripped, charging resumes only after the plug is pulled and reinserted, even when the pins have cooled; worn station plugs are a suspect. Mercedes stores P0E5F97 in the AC charger of several 2024 plug-in hybrids in strong sun and calls it no fault, with power cut back until the temperature drops.
