What P0D4F means
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.
P0D4F at a glance
- Check engine lightYes, usually on
- Emissions testNot an emissions code
- Limp modeNot expected
- Repair difficultyWorkshop only
- Typical labor0.5 to 4 hours
- Clears after repairAfter a drive cycle
Symptoms of P0D4F
- AC charging refused
- MIL on (GM)
- Charging interrupted with fault message
Common causes of P0D4F
- Most likelyVoltage sensor signal shorted to a supply voltage inside the charger
- Most likelyMeasuring stage of the on-board charger failed
- Less likelyCharger software misinterprets the signal
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of P0D4F means
| P | Powertrain system: engine, fuel system, ignition, emissions and transmission. |
| 0 | Generic code: it means the same on every make (SAE standard). |
| 4F | The exact fault in that area. |
What to do next
- Note P0D4F and any other codes stored with it: several codes together often point to one cause.
- Check for loose connectors and damaged wiring around the parts the code names.
- Check open recalls for your car: some faults are fixed for free by the dealer. Enter your VIN.
- Clear the code only after the repair. If it comes back, the fault is still there.
Buying a used car? Scan it for stored codes before you pay. A recently cleared memory can hide a problem.
Questions about P0D4F
What does P0D4F mean?
P0D4F means "Battery Charger Hybrid/EV Battery Output Voltage Sensor Circuit High". P0D4F is the high-side fault of the charger's output voltage sensor: the reading climbs beyond anything the battery could actually present. It is a generic code, so it means the same on every make.
Is it safe to drive with P0D4F?
Usually yes, for a short time, if the check engine light is steady and the car drives normally. If the light flashes or the car runs badly, stop and have it checked.
Will P0D4F fail an emissions test?
P0D4F is not an emissions code, so on its own it usually does not fail an emissions test. Other stored codes or a lit check engine light still can.
How hard is P0D4F to fix?
Difficulty: workshop only. A typical repair takes 0.5 to 4 hours of work. This is a job for a workshop.
Will P0D4F clear itself after the repair?
After the repair the car has to complete a drive cycle (a mix of city and highway driving) before the test runs again. Until then the readiness monitor shows "not ready", which can fail an inspection.
