P0D53 Battery Charger Hybrid/EV Battery Output Current Sensor Circuit Low

P0D53 is set when the charger's output current sensor reports a value below its valid floor. GM's charger module in the 2011 and 2014 Volt and the ELR uses a decoded current of 0.098 A or less, present for 400 of 500 ms with the low- and high-voltage sections awake; the fault is Type A, so the MIL lights after one trip, and the power checks P0D5C and P1ECE stay disabled while it is active. Mitsubishi defines it for the 2022 Outlander PHEV as a ground short once the sensor output falls under 2.349 V, equivalent to about -3.8 A, for 0.5 s; charging stops and the charger/DC-DC unit is to be replaced. The high counterpart is P0D54; offset errors are P0D52.

Likely causes

Current sensor output shorted to ground inside the charger
On-board charger measuring electronics failed
Supply of the current sensor missing

Symptoms

  • Charging stops or never begins
  • MIL on (GM)
  • Charging fault indicated at the charge port or in the cluster
