P2D00Motor Electronics Coolant Pump A Stuck/Stalled
- Generic OBD-II code · Powertrain
- Turns on the check-engine light
- Matters for the ITP
- Can trigger limp mode
- How the car detects it
- 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.
- What you may notice
- MIL on
- Reduced drive power when the inverter gets hot
- Hybrid system warning message
- Likely causes
- LikelyPump rotor or bearing seized
- PossibleBattery or powertrain controller software misreading the pump (Ford 2020 hybrids)
- PossibleDebris jamming the impeller after coolant work
- RarePump motor or integrated electronics failed
- Inspection (ITP)
- Matters for the ITP. While the check-engine light is on, the car fails the emissions check.
