What P0D6F means
P0D6F flags excessive current drawn by the electric A/C compressor on its high-voltage DC link while the motor is running. GM's first-generation Volt (2011–2015) and the 2016 Cadillac ELR set it when the DC link current exceeds 27 A in 30 of 60 samples taken every 50 ms with a compressor speed request above zero; it is Type B, MIL after two trips. A separate maker code, P1EC9, catches momentary peaks above 60 A. The second-generation Volt tables no longer list P0D6F. High current points to a mechanically binding or liquid-slugging compressor, a shorted motor winding or a failing power stage; overcharged refrigerant or very high head pressure can also raise the load. Phase-specific current faults are P0D7A to P0D7F.
P0D6F at a glance
- Check engine lightYes, usually on
- Emissions testNot an emissions code
- Limp modeNot expected
- Repair difficultyWorkshop only
- Typical labor1 to 5 hours
- Clears after repairAfter a drive cycle
Symptoms of P0D6F
- Check engine light after two trips
- Air conditioning cuts out under load
- Unusual noise from the compressor
Common causes of P0D6F
- Most likelyCompressor mechanically stiff or seizing
- PossibleShorted winding in the compressor motor
- PossibleRefrigerant overcharge or excessive high-side pressure
- Less likelyFailing power stage in the compressor inverter
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of P0D6F means
| P | Powertrain system: engine, fuel system, ignition, emissions and transmission. |
| 0 | Generic code: it means the same on every make (SAE standard). |
| 6F | The exact fault in that area. |
What to do next
- Note P0D6F 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 P0D6F
What does P0D6F mean?
P0D6F means "A/C Compressor Motor Current High". P0D6F flags excessive current drawn by the electric A/C compressor on its high-voltage DC link while the motor is running. It is a generic code, so it means the same on every make.
Is it safe to drive with P0D6F?
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 P0D6F fail an emissions test?
P0D6F 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 P0D6F to fix?
Difficulty: workshop only. A typical repair takes 1 to 5 hours of work. This is a job for a workshop.
Will P0D6F 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.
