P2BD6Motor Electronics Coolant Pump C Control Circuit High
- Generic OBD-II code · Powertrain
- Turns on the check-engine light
- Matters for the ITP
- Can trigger limp mode
- How the car detects it
- P2BD6 is stored when the control circuit of motor electronics coolant pump C reads higher than the commanded state allows. A short to battery voltage, or a driver stage that reports overcurrent, are the usual triggers; the pump may then keep running or ignore commands. No manufacturer documents P2BD6 publicly. Ford's 2019 hybrid summary shows how fast the pump A counterpart reacts: P0A07 sets after the output driver has signalled an overcurrent for just 0.25 s, which protects the stage early. GM's Volt and ELR tables fold a short to voltage on their equivalent pump line into P0CE9 (16 failures out of 20 checks spaced 250 ms apart, Type B). Ground faults on pump C are P2BD5, an open line P2BD4. A warning and reduced power follow if cooling suffers.
- What you may notice
- Hybrid system or check engine warning
- Pump C keeps running after the vehicle is switched off, or does not respond at all
- Power limitation during long climbs or fast driving
- Likely causes
- LikelyControl wire of pump C shorted to a supply wire in the harness
- PossiblePump C drawing excessive current because of an internal electrical fault
- PossibleBent or corroded pins in the pump C connector touching each other
- RareFailed output stage in the controlling module
- Inspection (ITP)
- Matters for the ITP. While the check-engine light is on, the car fails the emissions check.
