P2D0DMotor Electronics Coolant Pump C Supply Voltage Circuit
- Generic OBD-II code · Powertrain
- Turns on the check-engine light
- Matters for the ITP
- Can trigger limp mode
- How the car detects it
- P2D0D flags the supply side of motor electronics coolant pump C: the voltage on its power feed is outside the permitted window or missing. Its counterparts on the command line are P2BD4 (open), P2BD5 (low) and P2BD6 (high), so a technician who sees P2D0D alone should check the fuse, relay, power splice and ground of pump C before touching the signal wire. No manufacturer publicly documents P2D0D. For comparison, Ford's 2019 hybrid summary runs the pump A circuit checks only while system voltage stays between 6 and 19 V, and its 2024 summary lists supply voltage out of range (1C) as an auxiliary pump fault type with an 11 V threshold. CARB requires the electrical monitoring of all inverter cooling outputs. A pump C without a stable feed may stop, so the cooled branch warms and power is limited.
- What you may notice
- Warning lamp on
- Pump C runs intermittently or not at all
- Other voltage-related codes stored at the same time
- Likely causes
- LikelyPoor ground or corroded supply terminal at pump C
- PossibleBlown fuse or faulty relay in the pump C feed
- PossibleWeak 12 V battery or low DC/DC converter output
- Inspection (ITP)
- Matters for the ITP. While the check-engine light is on, the car fails the emissions check.
- Repair
- Medium · Often possible to do yourself.Typical cost: €20 – €600
