P0E88Battery Charger B Input Current Too Low
- Generic OBD-II code · Powertrain
- How the car detects it
- P0E88 is set when charger B takes in less current than it should for the charging power it is asked to deliver, with voltage present. Its counterpart without a letter is P0D29. No manufacturer documents P0E88 in public sources. The neighbour P0E89 for too much current is documented by Ford, Toyota, Isuzu and Mercedes, so the input current of a B charger is clearly monitored. A low value with normal voltage suggests that the charger does not ramp up, that a resistive inlet or cable limits the flow, or that the charging station offers less current than expected. A measurement error is possible too, but those have their own sensor codes (P0E8A). CARB requires charger faults that limit the charging rate to be detected. Usually charging is just slow; driving is not affected.
- What you may notice
- AC charging takes much longer than usual
