What P0E5E means
P0E5E reports that the processor of the on-board charger's control unit fails its self-tests. Mitsubishi spells this out for the 2023 Outlander PHEV: P0E5E-00 means a ROM checksum (CRC) error or a RAM read/write error in the charger control; the code lights both the PHEV warning and the MIL. In the Volkswagen group the code is stored by the battery management module (address 8C). Bentley's information 2066497/1 for the 2021 Bentayga Hybrid lists it with charger faults when the car will not charge or stops charging, and the remedy there is a new on-board charger (AX4). Audi's on-car analysis list of June 2026 names P0E5E00 for Q5 PHEV 2024–2025 with a check engine light after charging and asks dealers to contact technical support. Non-processor faults of the module are P0D67.
P0E5E at a glance
- Check engine lightYes, usually on
- Emissions testNot an emissions code
- Limp modeNot expected
- Repair difficultyWorkshop only
- Typical labor0.5 to 5 hours
- Clears after repairWhen cleared with a scanner
Symptoms of P0E5E
- Plug-in charging impossible or interrupted
- MIL and hybrid/PHEV warning, sometimes right after charging
Common causes of P0E5E
- Most likelyControl electronics of the on-board charger defective (unit replacement)
- PossibleCorrupt or outdated charger software
- Less likelyUnstable 12 V supply or ground of the charger during start-up
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of P0E5E means
| P | Powertrain system: engine, fuel system, ignition, emissions and transmission. |
| 0 | Generic code: it means the same on every make (SAE standard). |
| 5E | The exact fault in that area. |
What to do next
- Note P0E5E 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 P0E5E
What does P0E5E mean?
P0E5E means "Battery Charger Control Module A Processor Performance". P0E5E reports that the processor of the on-board charger's control unit fails its self-tests. It is a generic code, so it means the same on every make.
Is it safe to drive with P0E5E?
Usually yes, for a short time, if the check engine light is steady and the car drives normally. If the light flashes or the car runs badly, stop and have it checked.
Will P0E5E fail an emissions test?
P0E5E 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 P0E5E to fix?
Difficulty: workshop only. A typical repair takes 0.5 to 5 hours of work. This is a job for a workshop.
Will P0E5E clear itself after the repair?
Clear the code with a scanner after the repair. If the fault is fixed, it does not come back.
