P0D4EBattery Charger Hybrid/EV Battery Output Voltage Sensor Circuit Low
- Generic OBD-II code · Powertrain
- Turns on the check-engine light
- Needs a drive cycle to confirm a fix
- How the car detects it
- P0D4E reports a signal below the valid range for the sensor measuring the charger's DC output toward the traction battery. In GM's charger module for the 2011-2014 Volt and ELR the raw value must stay at or below 2.62 V for 400 of 500 ms; the fault is Type A and lights the MIL at once. The 2016-2019 Volt reads the sensor as a duty cycle and treats 8 % or less, or a signal stuck at 100 %, as low, Type B. Mitsubishi's 2022 Outlander PHEV calls it a short to ground: under 0.943 V, equal to about -7 V, for 0.5 s; charging is stopped and the charger/DC-DC unit is replaced. GM's Bolt EI PIE0828 also lists the code. Its counterpart is P0D4F; plausibility errors fall under P0D4D.
