P0D2D: Drive Motor A Inverter Voltage Sensor A Circuit

What does P0D2D mean?

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.

The code tells you which monitor failed, not which part is broken. Test before replacing parts.

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)

Common causes

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

Likelihood is a general estimate across vehicles; your make and model may differ.
