P0D7D 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. 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.

Likely causes

Phase V current sensor reading negative at standstill
Fault in the inverter's current evaluation

Symptoms

  • Check engine light after two trips
  • No cooling from the air conditioning
  • Battery cooling via refrigerant may be limited
