P0EEBBattery Charger Coupler Temperature Sensor B Circuit Intermittent/Erratic
- Generic OBD-II code · Powertrain
- How the car detects it
- P0EEB catches a sensor B signal from the charging inlet that jumps or drops out for moments. A metal contact and its plastic housing have real thermal mass, so a change of many degrees within milliseconds cannot be a true temperature and points to the circuit. No manufacturer documents P0EEB publicly. A Mercedes bulletin about the first inlet sensor of the third-generation smart with its optional 22 kW unit fits the pattern: inlet sensor codes there came from loose low-voltage contacts at the charger, the fix was to work the plugs gently and watch whether charging starts, and the bulletin warns the fault may only appear with warm or cold parts at the start or end of charging. Typical for P0EEB is a session that stops without visible reason and works next time. Steady faults are P0EE9 and P0EEA.
- What you may notice

- PossibleMoisture that comes and goes in the inlet connector
- RareCracked sensor element with temperature-dependent contact
- Repair
- Medium · Usually a job for a workshop.Typical cost: €50 – €1,200
