P0D38 is the general circuit code for the sensor that measures the AC current entering battery charger A, the on-board charger. It sets when the signal is missing or electrically invalid; range, low, high and intermittent faults have their own codes P0D39-P0D3C. No manufacturer documents P0D38 with set conditions in a public source. Mitsubishi's checks on the sibling codes show the scale: on the 2022 Outlander PHEV a sensor output below 0.344 V or above 4.658 V, about 54 A either way, for 0.5 s stops charging and leads to replacing the combined charger and DC/DC unit. Delta Electronics describes a self-test of a charger's current detection before power flows. Unlike P0D29 and P0D2A, which judge the current itself, P0D38 concerns the measurement. Charging is refused or aborted; driving stays possible.

Likely causes

Current sensing inside the on-board charger failed
Open or shorted sensor wiring or connector
Charger software or supply voltage fault

Symptoms

  • AC charging does not start or stops
  • Charging fault indication on the dashboard or charge port
