P2D83 says the current sensor at the input of charger B outputs a signal under its valid range. No manufacturer documents P2D83 publicly. For charger A the same fault is P0D3A, which Mitsubishi interprets on the 2022 Outlander PHEV as a ground short. Below 0.344 V of sensor output (roughly -54 A) for half a second, with 10-16 V on the charger, ends the charge, and the repair is a replacement charger/DC-DC assembly. In GM's 2011 Volt, the charger module treats an AC reading below 0.8 A in 160 out of 200 ms as Type A. Toyota's RAV4 Prime proves that a B stage has its own input current monitoring. The sensor usually sits inside the charger. Too high is P2D84, implausible values P2D85, the general circuit code P0E8A.

Likely causes

Current sensor of charger B or its signal path shorted to ground inside the unit
Sensor supply inside the charger missing
Damaged internal connection or external harness where the sensor is separate

Symptoms

  • AC charging aborts shortly after starting
  • Reduced charging power if only charger A is still used
