P2D0A Motor Electronics Coolant Pump C Stuck/Stalled

P2D0A starts the five codes for pump C, a third electric pump that some layouts add to the motor electronics loop, for example for a further drive unit or a separate charger and DC/DC branch. The code means pump C is driven and powered but its rotor stays still. Seized bearings, foreign bodies in the impeller and burnt windings are the usual mechanical and electrical reasons. No manufacturer publicly documents P2D0A, and none of the other pump C codes in this block appear in public service material either. CARB requires monitoring of every electronic output used for inverter cooling; Ford's 2024 summary records the matching fault type (71, actuator stuck), and the pump A equivalent P2D00 is known from 2020 Ford hybrids. For a pump C wiring fault use P2BD4 to P2BD7 instead. Without flow the cooled branch heats up and power is reduced.

Likely causes

Seized bearing or blocked rotor in pump C
Foreign bodies or deposits jamming the impeller
Burnt motor winding or failed start electronics in the pump

Symptoms

  • Warning lamp on
  • Pump C silent while commanded on
  • Rising temperature in the branch cooled by pump C and reduced power
