What P2BD6 means
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.
P2BD6 at a glance
- Check engine lightYes, usually on
- Emissions testCan fail
- Limp modePossible
- Repair difficultyMedium
- Typical labor0.5 to 3 hours
- Clears after repairWhen cleared with a scanner
Symptoms of P2BD6
- 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
Common causes of P2BD6
- Most 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
- Less likelyFailed output stage in the controlling module
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of P2BD6 means
| P | Powertrain system: engine, fuel system, ignition, emissions and transmission. |
| 2 | Generic code (second SAE range): it means the same on every make. |
| B | Area: hybrid propulsion. |
| D6 | The exact fault in that area. |
What to do next
- Note P2BD6 and any other codes stored with it: several codes together often point to one cause.
- Check for loose connectors and damaged wiring around the parts the code names.
- Check open recalls for your car: some faults are fixed for free by the dealer. Enter your VIN.
- Clear the code only after the repair. If it comes back, the fault is still there.
Buying a used car? Scan it for stored codes before you pay. A recently cleared memory can hide a problem.
Questions about P2BD6
What does P2BD6 mean?
P2BD6 means "Motor Electronics Coolant Pump C Control Circuit High". P2BD6 is stored when the control circuit of motor electronics coolant pump C reads higher than the commanded state allows. It is a generic code, so it means the same on every make.
Is it safe to drive with P2BD6?
Drive gently and only to a workshop. With P2BD6 the car can go into limp mode (reduced power) to protect itself.
Will P2BD6 fail an emissions test?
Yes, it can. P2BD6 is emissions-related, so most inspection programs fail a car while it is stored or while the check engine light is on.
How hard is P2BD6 to fix?
Difficulty: medium. A typical repair takes 0.5 to 3 hours of work. This is a job for a workshop.
Will P2BD6 clear itself after the repair?
Clear the code with a scanner after the repair. If the fault is fixed, it does not come back.
