P2D00 Motor Electronics Coolant Pump A Stuck/Stalled

P2D00 reports that coolant pump A of the motor electronics loop, which cools the inverter and drive-motor electronics, does not rotate although commanded. It opens its own series P2D00–P2D0E (stuck, overspeed/air, underspeed, supply voltage and module overtemperature for pumps A to C) and should not be confused with the Hybrid/EV electronics pump codes P2C66–P2C68. Ford uses P2D00 on 2020 hybrids: bulletins 20-2221 (Escape HEV, stored in the BECM) and 20-2345 (Explorer, Aviator, Police Interceptor Utility, stored in the PCM) list it with P2D01–P2D04 and fix it by reprogramming after the coolant level has been checked. Without a software cause, a seized rotor or debris is behind it. Without flow the inverter heats up and the system derates power.

Likely causes

Pump rotor or bearing seized
Battery or powertrain controller software misreading the pump (Ford 2020 hybrids)
Debris jamming the impeller after coolant work
Pump motor or integrated electronics failed

Symptoms

  • MIL on
  • Reduced drive power when the inverter gets hot
  • Hybrid system warning message
