P2D04Motor Electronics Coolant Pump A Control Module Overtemperature
- Generic OBD-II code · Powertrain
- Turns on the check-engine light
- Matters for the ITP
- Can trigger limp mode
- How the car detects it
- P2D04 refers to the small electronics built into coolant pump A of the motor electronics loop: its own temperature has exceeded the limit, and the pump usually reports this before cutting back or switching off to protect itself. Heat builds up when the pump works hard against a restriction, runs dry, sits close to a hot component or has an internal electrical fault. Ford's 2019 hybrid summary still lumped such internal reports under P0C73 (confirmed pump fault for more than 1.25 s); Ford's 2020 hybrid campaigns for the Escape (20-2221) and for Explorer, Aviator and the police utility (20-2293, later 20-2345) name P2D04 separately and fix it with a software update once the coolant level is right. Ford's 2024 summary calls the type 98, system overtemperature. If the pump shuts down, the inverter may overheat and power drops.
- What you may notice
- Malfunction indicator lamp on, sometimes only after longer drives or in hot weather
- Pump stops temporarily and restarts after cooling down
- Inverter overtemperature warning or reduced power
- Likely causes
- PossiblePump running dry or with too little coolant, so it loses its own cooling
- PossibleBlocked or kinked line forcing the pump to work at high load
- PossibleInternal fault in the pump control electronics
- RareSoftware strategy on 2020 Ford hybrids, cured by reprogramming
- Inspection (ITP)
- Matters for the ITP. While the check-engine light is on, the car fails the emissions check.
