What P0D3F means
P0D3F reports that the charger's AC input voltage reading is too low. In the 2011-2014 Volt GM's charger module sets it when the AC peak stays below 90 V while AC is present (1.5 s in 2011, 5.5 s in 2014), Type A; the 2016-2019 Volt instead watches a duty-cycle signal at or below 8 %. GM bulletin PIC5803D links it to certain charging stations and to grid brown-outs during storms, 12-08-45-001A to electrical noise on household circuits, and PIT6353 to DC-only NACS adapters plugged into AC chargers on newer GM EVs. Mitsubishi's Outlander PHEV treats a sensor output under 0.474 V as a short to ground and stops charging. The opposite fault is P0D40. Check the supply and the charging equipment before replacing parts.
P0D3F at a glance
- Check engine lightYes, usually on
- Emissions testNot an emissions code
- Limp modeNot expected
- Repair difficultyMedium
- Typical labor0.3 to 4 hours
- Clears after repairWhen cleared with a scanner
Symptoms of P0D3F
- Charging does not start or is interrupted
- MIL on (GM)
- Charge cord LEDs flash or the charge indicator changes color repeatedly
Common causes of P0D3F
- Most likelyWeak, interrupted or noisy AC supply (brown-out, shared circuit)
- PossibleDC-only adapter used on an AC charger (GM PIT6353)
- PossibleCharger module software needs update (GM PIC5803D)
- Less likelyVoltage sensor signal shorted to ground in the charger
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of P0D3F means
| P | Powertrain system: engine, fuel system, ignition, emissions and transmission. |
| 0 | Generic code: it means the same on every make (SAE standard). |
| 3F | The exact fault in that area. |
What to do next
- Note P0D3F 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 P0D3F
What does P0D3F mean?
P0D3F means "Battery Charger A Input Voltage Sensor A Circuit Low". P0D3F reports that the charger's AC input voltage reading is too low. It is a generic code, so it means the same on every make.
Is it safe to drive with P0D3F?
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 P0D3F fail an emissions test?
P0D3F 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 P0D3F to fix?
Difficulty: medium. A typical repair takes 0.3 to 4 hours of work. This is a job for a workshop.
Will P0D3F clear itself after the repair?
Clear the code with a scanner after the repair. If the fault is fixed, it does not come back.
