What P2B67 means
P2B67 means the control line of coolant pump D sits too low, typically because it is shorted to ground or the driver stage sees excess current. No manufacturer publishes this code. Ford's comparable entries for pumps A and B (P2602, P261C) set when the smart driver in the engine computer reports an output fault, checked continuously above 11 V. Chafed insulation against body or engine, water in the connector and an internally shorted pump input are the usual suspects. Depending on how the output is wired, a ground short can leave the pump running nonstop or silence it completely. With the pump unplugged, measure the resistance of the signal wire to ground before replacing parts. Open circuit is P2B66, short to voltage P2B68; pump C has P26F5.
P2B67 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 P2B67
- Warning lamp with stored code
- Pump D runs constantly or not at all
Common causes of P2B67
- Most likelyControl wire chafed through and shorted to ground
- PossibleMoisture or corrosion in the pump connector
- Less likelyControl input inside the pump shorted
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of P2B67 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. |
| 67 | The exact fault in that area. |
What to do next
- Note P2B67 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 P2B67
What does P2B67 mean?
P2B67 means "Coolant Pump D Control Circuit Low". P2B67 means the control line of coolant pump D sits too low, typically because it is shorted to ground or the driver stage sees excess current. It is a generic code, so it means the same on every make.
Is it safe to drive with P2B67?
Drive gently and only to a workshop. With P2B67 the car can go into limp mode (reduced power) to protect itself.
Will P2B67 fail an emissions test?
Yes, it can. P2B67 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 P2B67 to fix?
Difficulty: medium. A typical repair takes 0.5 to 3 hours of work. This is a job for a workshop.
Will P2B67 clear itself after the repair?
Clear the code with a scanner after the repair. If the fault is fixed, it does not come back.
