P0D39 flags an implausible reading from the sensor that measures alternating current at the input of charger A, the on-board charger. Both documented users test its zero point. GM's charger module in the 2011 Volt sets the code as a Type A fault with MIL when the current value sits 5.4 A or more away from zero for 512 of 640 ms although no current should flow; the 2016 ELR table uses 1.4 A. Mitsubishi's 2022 Outlander PHEV logs it when 1.5 A or more is seen for 2 s while the PHEV-ECU has not released charging, then stops charging and calls for a new charger/DC-DC unit. Hard electrical faults of the same sensor are P0D3A and P0D3B, the general circuit code is P0D38. The car still drives, but AC charging is blocked.

Likely causes

Zero point of the current sensor inside the charger has drifted
Measuring electronics of the on-board charger failed
Charger calibration out of date

Symptoms

  • AC charging does not start
  • MIL on (GM)
  • Charging fault shown at the charge port or in the cluster
