P0D7DA/C Compressor Motor Phase V Current High
- Generic OBD-II code · Powertrain
- Turns on the check-engine light
- Needs a drive cycle to confirm a fix
- How the car detects it
- 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.
