P0D4FBattery Charger Hybrid/EV Battery Output Voltage Sensor Circuit High

  • Generic OBD-II code · Powertrain
  • Turns on the check-engine light
  • Needs a drive cycle to confirm a fix
How the car detects it
P0D4F is the high-side fault of the charger's output voltage sensor: the reading climbs beyond anything the battery could actually present. GM's 2011-2014 charger module for the Volt and ELR flags a decoded value of 482 V or more for 400 of 500 ms as a Type A fault with immediate MIL. In the 2016-2019 Volt the sensor delivers a pulse-width signal; 92 % duty cycle or more, or a line resting at 0 %, counts as high and is rated Type B. For the 2022 Outlander PHEV Mitsubishi sets the code at a sensor voltage above 3.5 V, about 632 V, held for 0.5 s, describes it as a short to supply, stops charging and replaces the charger/DC-DC unit. GM's Bolt EI PIE0828 names it too. The low counterpart is P0D4E.
What you may notice
  • AC charging refused
  • MIL on (GM)
  • Charging interrupted with fault message
Likely causes
  • LikelyVoltage sensor signal shorted to a supply voltage inside the charger
  • LikelyMeasuring stage of the on-board charger failed
  • RareCharger software misinterprets the signal
