P2D0CMotor Electronics Coolant Pump C Underspeed
- Generic OBD-II code · Powertrain
- Turns on the check-engine light
- Matters for the ITP
- Can trigger limp mode
- How the car detects it
- P2D0C tells you that pump C, the third pump of the motor electronics loop, is turning too slowly for longer than its controller accepts. Compared with P2D0A the rotor is free, and compared with P2D0B the problem is lack of speed, not lack of load: think of a dragging bearing, a partly clogged impeller or filter screen, or a feed that cannot hold its voltage while the motor draws current. No manufacturer publicly documents P2D0C. Ford's 2024 summary separates under-speed (B2) from the other auxiliary pump faults and runs the check for 5 s once the battery has at least 11 V; on pump A, Ford's 2020 hybrids record the same failure as P2D02. CARB requires a functional check of inverter cooling outputs where feasible. Rising component temperatures and reduced power follow.
- What you may notice
- Warning lamp on
- Pump C speed below target in live data
- Higher component temperatures and power limits under load
- Likely causes
- PossibleDragging bearing or internal friction in pump C
- PossiblePartly clogged impeller or screen in the pump C branch
- PossibleVoltage drop on feed or ground of pump C under load
- Inspection (ITP)
- Matters for the ITP. While the check-engine light is on, the car fails the emissions check.
