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.
High severity. Can I keep driving?If the car still runs, drive as little as possible and go to a specialized repair shop. Do not touch the orange cables: they carry high voltage.
Symptoms
- Charging reduced or aborted
- Fault only at certain stations
Most likely causes
- Worn station plug heating one contact unevenly
- Drifting sensor element B
- Sensor B lost thermal contact to its pin
What to check, in order
Start with the simplest. You can tick off each step.
Good to know
- Repair difficulty: medium
What each character of P0EE8 means
- P: Powertrain: engine and transmission
- 0: Generic code: same on every make
- E: Subsystem depends on the code range
- E8: Specific fault in that system
Frequently asked questions
Can I keep driving with code P0EE8?
If the car still runs, drive as little as possible and go to a specialized repair shop. Do not touch the orange cables: they carry high voltage.
What causes code P0EE8?
The most common causes are: worn station plug heating one contact unevenly; drifting sensor element B; sensor B lost thermal contact to its pin.
