Drive motor A's inverter measures the DC link voltage it switches, and voltage sensor A is the channel that passes this value to the motor controller. P0D2D is the general circuit fault for that channel: the signal is missing or electrically unusable, without a more specific low or high verdict. Ford lists P0D2D among its MIL codes. On 2021 Mustang Mach-E vehicles it could be stored in secondary on-board control module C after charging, when a remote start ended in a no-start; customer satisfaction program 21B02 cured this with new software for the PCM and associated modules. Without a trusted bus voltage the controller usually limits or blocks electric drive. Plausibility faults are P0D2E, low and high signals P0D2F/P0D30, short dropouts P0D31.

Likely causes

Inverter or powertrain module software fault (Ford 21B02)
Loose connector or damaged signal wiring of the voltage sensor
Voltage sensing circuit inside the inverter failed

Symptoms

  • Hybrid or EV system warning and MIL
  • Vehicle does not become ready to drive or electric drive is reduced
  • No start after charging and remote start (Mach-E)
