P0DFE code meaning
Battery Charger Coolant Control Valve Control Circuit Low
What P0DFE means
P0DFE means the control line of the charger coolant valve reads low, usually because it is shorted to ground somewhere between driver and valve. No manufacturer documents P0DFE publicly. GM's 2011 Volt tables show how such a check works on battery coolant valve A (P0CE2): with system voltage above 9 V and the valve commanded in reverse, a low sense level on drive 1 counts as a failure, and the code needs a fault in 90 of 100 checks spaced 6.25 ms apart before it is set as a two-trip Type B code. For the charger valve a similar logic is likely but not published. A ground short typically freezes the valve where it is, so the charger may be left without coolant and lower its power. Look for chafed wires and wet connectors. Open circuit is P0DFD.
P0DFE at a glance
- Check engine lightUsually not
- Emissions testNot an emissions code
- Limp modeNot expected
- Repair difficultyMedium
- Typical labor0.5 to 2.5 hours
- Clears after repairWhen cleared with a scanner
Symptoms of P0DFE
- Reduced charging power, longer charging time
- Charger warning or charging stops
- Driving normally unaffected
Common causes of P0DFE
- Most likelyControl wire chafed through and shorted to ground
- PossibleCoolant or water in the valve connector
- PossibleInternal short in the valve actuator
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of P0DFE means
| P | Powertrain system: engine, fuel system, ignition, emissions and transmission. |
| 0 | Generic code: it means the same on every make (SAE standard). |
| FE | The exact fault in that area. |
What to do next
- Note P0DFE 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 P0DFE
What does P0DFE mean?
P0DFE means "Battery Charger Coolant Control Valve Control Circuit Low". P0DFE means the control line of the charger coolant valve reads low, usually because it is shorted to ground somewhere between driver and valve. It is a generic code, so it means the same on every make.
Is it safe to drive with P0DFE?
P0DFE does not normally turn on the check engine light by itself. Watch for the symptoms above and have it checked soon.
Will P0DFE fail an emissions test?
P0DFE 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 P0DFE to fix?
Difficulty: medium. A typical repair takes 0.5 to 2.5 hours of work. This is a job for a workshop.
Will P0DFE clear itself after the repair?
Clear the code with a scanner after the repair. If the fault is fixed, it does not come back.
