P0EE8Battery Charger Coupler Temperature Sensor B Circuit Range/Performance
- Generic OBD-II code · Powertrain
- Needs a drive cycle to confirm a fix
- How the car detects it
- P0EE8 is set when sensor B in the charging inlet delivers an electrically valid value that does not fit the situation. A plausibility test may compare it with sensor A on the neighbouring pin, with the outside temperature after a long rest, or with the heating expected for the charge current. If B reads far colder than A during a high-current session, or shows a sudden rise without current, it fails. No manufacturer documents P0EE8 publicly. GM gives a hint for the A sensor equivalent P0D9A on the 2022 Hummer EV and BrightDrop EV600: worn or oversized terminals in public charge plugs are a suspect, and the test only runs again after about ten minutes of driving above 2 mph (PIT5904). Inlets with two DC pin sensors, as Sailtran builds them, make such a cross-check possible.
