P0D40 is the high-signal fault of the charger's input voltage sensor. GM's Volt charger module (2011 and 2014 tables) sets it when the measured AC peak exceeds 422 V for 160 of 200 ms and lights the MIL as a Type A fault; in the 2016 and 2019 Volt the controller reads a duty-cycle signal and fails it at 92 % and above or at a constant 0 %, Type B over two trips. Mitsubishi's 2022 Outlander PHEV reads a sensor voltage above 3.161 V, corresponding to more than 492 V, for 0.5 s as a short to power, stops charging and replaces the charger/DC-DC unit. Household and Level 2 supplies do not reach these values, so the sensor path or the signal line is normally to blame. P0D3F is the low counterpart.

Likely causes

Voltage sensor signal shorted to supply inside the charger
Open duty-cycle signal line between charger and controller (2016-2019 Volt)
Failed on-board charger

Symptoms

  • AC charging is refused
  • MIL on (GM)
