P0E5EBattery Charger Control Module A Processor Performance
- Generic OBD-II code · Powertrain
- Turns on the check-engine light
- How the car detects it
- 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.
