P0D52 Battery Charger Hybrid/EV Battery Output Current Sensor Circuit Range/Performance

P0D52 flags an output current reading that lies inside the sensor's range yet cannot be right. Mitsubishi documents the check for the 2022 Outlander PHEV as a zero-point test: while the PHEV-ECU has not granted charging, no current should leave the charger, so an absolute reading of 1.5 A or more lasting 1 s sets the code; charging is halted and the charger/DC-DC unit is replaced. Kia includes P0D52 in bulletin 298 for the 2023 Niro EV, where the active code calls for replacing the integrated charging unit (ICCU). GM's Volt does not use P0D52 and instead judges current plausibility through its power balance P0D5C. Electrical out-of-range faults are P0D53 and P0D54; the circuit code is P0D51.

Likely causes

Zero point of the output current sensor has drifted
Charger or integrated charging unit (Kia ICCU) failed
Outdated charger software

Symptoms

  • Poor or no AC charging
  • MIL or electric system warning (Kia)
  • DC fast charging may still work (Kia)
