P0EE7 code meaning
Battery Charger Coupler Temperature Sensor B Circuit
What P0EE7 means
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.
P0EE7 at a glance
- Check engine lightUsually not
- Emissions testNot an emissions code
- Limp modeNot expected
- Repair difficultyMedium
- Typical labor0.5 to 3 hours
- Clears after repairWhen cleared with a scanner
Symptoms of P0EE7
- Charging refused or stopped
- Charge indicator shows a fault
Common causes of P0EE7
- Most likelyLoose low-voltage connector between inlet and charger
- PossibleDamaged sensor wire in the inlet harness
- Less likelyFailed sensor element B (usually means a new inlet)
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of P0EE7 means
| P | Powertrain system: engine, fuel system, ignition, emissions and transmission. |
| 0 | Generic code: it means the same on every make (SAE standard). |
| E7 | The exact fault in that area. |
What to do next
- Note P0EE7 and any other codes stored with it: several codes together often point to one cause.
- Check for loose connectors and damaged wiring around the parts the code names.
- Check open recalls for your car: some faults are fixed for free by the dealer. Enter your VIN.
- Clear the code only after the repair. If it comes back, the fault is still there.
Buying a used car? Scan it for stored codes before you pay. A recently cleared memory can hide a problem.
Questions about P0EE7
What does P0EE7 mean?
P0EE7 means "Battery Charger Coupler Temperature Sensor B Circuit". P0EE7 is the general circuit code for the second temperature sensor of the charging inlet. It is a generic code, so it means the same on every make.
Is it safe to drive with P0EE7?
P0EE7 does not normally turn on the check engine light by itself. Watch for the symptoms above and have it checked soon.
Will P0EE7 fail an emissions test?
P0EE7 is not an emissions code, so on its own it usually does not fail an emissions test. Other stored codes or a lit check engine light still can.
How hard is P0EE7 to fix?
Difficulty: medium. A typical repair takes 0.5 to 3 hours of work. This is a job for a workshop.
Will P0EE7 clear itself after the repair?
Clear the code with a scanner after the repair. If the fault is fixed, it does not come back.
