P0EEB code meaning
Battery Charger Coupler Temperature Sensor B Circuit Intermittent/Erratic
What P0EEB means
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.
P0EEB at a glance
- Check engine lightUsually not
- Emissions testNot an emissions code
- Limp modeNot expected
- Repair difficultyMedium
- Typical labor0.5 to 4 hours
- Clears after repairWhen cleared with a scanner
Symptoms of P0EEB
- Charging stops sporadically
- Fault cannot be reproduced at once
Common causes of P0EEB
- Most likelyLoose contact in the sensor B circuit or at the charger plug
- PossibleMoisture that comes and goes in the inlet connector
- Less likelyCracked sensor element with temperature-dependent contact
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of P0EEB means
| P | Powertrain system: engine, fuel system, ignition, emissions and transmission. |
| 0 | Generic code: it means the same on every make (SAE standard). |
| EB | The exact fault in that area. |
What to do next
- Note P0EEB 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 P0EEB
What does P0EEB mean?
P0EEB means "Battery Charger Coupler Temperature Sensor B Circuit Intermittent/Erratic". P0EEB catches a sensor B signal from the charging inlet that jumps or drops out for moments. It is a generic code, so it means the same on every make.
Is it safe to drive with P0EEB?
P0EEB does not normally turn on the check engine light by itself. Watch for the symptoms above and have it checked soon.
Will P0EEB fail an emissions test?
P0EEB 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 P0EEB to fix?
Difficulty: medium. A typical repair takes 0.5 to 4 hours of work. This is a job for a workshop.
Will P0EEB clear itself after the repair?
Clear the code with a scanner after the repair. If the fault is fixed, it does not come back.
