What P0D7D means
P0D7D marks a phase V current reading of the electric A/C compressor that is far negative while the motor should be idle. GM's first-generation Volt and the 2016 ELR set it at −68 A or less, judged in 30 of 60 samples every 50 ms whenever the speed request is zero, as Type B with MIL after two trips. A 12 V reset is needed before the diagnostic can report a pass again. Because the check runs only with the motor stopped, it catches a drifting or failed current sensor rather than an operating overload; running overcurrent is P0D6F. Expect the climate control to lose cooling, with battery cooling affected on vehicles that share the refrigerant circuit. The counterpart on the same phase is P0D7C.
P0D7D 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 P0D7D
- Check engine light after two trips
- No cooling from the air conditioning
- Battery cooling via refrigerant may be limited
Common causes of P0D7D
- Most likelyPhase V current sensor reading negative at standstill
- PossibleFault in the inverter's current evaluation
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of P0D7D means
| P | Powertrain system: engine, fuel system, ignition, emissions and transmission. |
| 0 | Generic code: it means the same on every make (SAE standard). |
| 7D | The exact fault in that area. |
What to do next
- Note P0D7D 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 P0D7D
What does P0D7D mean?
P0D7D means "A/C Compressor Motor Phase V Current High". P0D7D marks a phase V current reading of the electric A/C compressor that is far negative while the motor should be idle. It is a generic code, so it means the same on every make.
Is it safe to drive with P0D7D?
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 P0D7D fail an emissions test?
P0D7D 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 P0D7D to fix?
Difficulty: workshop only. A typical repair takes 1 to 5 hours of work. This is a job for a workshop.
Will P0D7D 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.
