P0EE7Battery Charger Coupler Temperature Sensor B Circuit
- Generic OBD-II code · Powertrain
- How the car detects it
- P0EE7 is the general circuit code for the second temperature sensor of the charging inlet. High-current inlets carry several sensors; the supplier Sailtran fits one PT1000 at the L1 pin and two independent PT1000 at DC+ and DC- of its CCS2 inlet, so A and B often stand for two different contacts. The code applies when the sensor B circuit is faulty in a way the module does not sort into low, high or implausible. No manufacturer documents P0EE7 on an official server. For sensor A, Mercedes lists P0D9900 as an electrical fault of the inlet contact sensor on the smart electric drive with 22 kW charger and traces it to loose low-voltage plugs at the charger (LI54.10-P-067823). CARB requires plug-in charger faults that stop or slow charging to be found. Sensor A is P0D99.
