P0E89Battery Charger B Input Current Too High
- Generic OBD-II code · Powertrain
- Turns on the check-engine light
- How the car detects it
- P0E89 reports more input current into charger B than permitted, and it is the best documented code of this series. Toyota lists P0E8919 on 2021 to 2023 RAV4 Prime XSE models with the 6.6 kW charger, together with P0D2A19 and PFC boost faults; the MIL is on, plug-in charging fails and the charger assembly is replaced (T-SB-0067-22). Ford's plug-in summary sets it when the charger, in ready state, receives a charging current request above 100 A. Isuzu logs it as excessive on-board charger input current in the VCU of the 2025-2026 NRR-EV with an amber EV warning and cures it with a VCU recalibration. Mercedes uses P0E8929 in the DC charging unit of several plug-in hybrids and the eSprinter, where the vehicle may refuse to start once a DC fast charge has ended. Too little current is P0E88.
