P0D39Battery Charger A Input Current Sensor Circuit Range/Performance
- Generic OBD-II code · Powertrain
- Turns on the check-engine light
- How the car detects it
- 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.
- What you may notice
- AC charging does not start
- MIL on (GM)
- Charging fault shown at the charge port or in the cluster
- Likely causes
- LikelyZero point of the current sensor inside the charger has drifted
- PossibleMeasuring electronics of the on-board charger failed
- RareCharger calibration out of date
