What P261D means
With P261D the module finds the drive of coolant pump B too high, either a short to the supply side or a current above the permitted limit. VW's 2014 Touareg book uses a current test here, roughly 2.2 to 4 A as the threshold. Ford checks the component-cooling pump B of the high-temperature loop through a smart driver that reports output faults within 5 s at 11 V or more. GM's 2014-2018 hybrid tables include P261D in two fault bundles of the switchable water pump, one for control faults and one for a pump that keeps flowing. A sticking, overloaded pump can draw excess current as well, so check the pump before the module. P261A is the open circuit, P261C the low-side fault.
P261D at a glance
- Check engine lightYes, usually on
- Emissions testCan fail
- Limp modeNot expected
- Repair difficultyMedium, DIY possible
- Typical labor0.5 to 2.5 hours
- Clears after repairWhen cleared with a scanner
Symptoms of P261D
- Malfunction indicator lamp on
- Pump switched off for protection or running permanently
- Possible battery drain if the pump keeps running after shutdown
Common causes of P261D
- Most likelyStiff or partly seized pump drawing excess current
- PossibleControl wire shorted to a battery-voltage circuit
- Less likelyFaulty driver stage in the engine module
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of P261D means
| P | Powertrain system: engine, fuel system, ignition, emissions and transmission. |
| 2 | Generic code (second SAE range): it means the same on every make. |
| 6 | Area: computer (engine control module) and output circuits. |
| 1D | The exact fault in that area. |
What to do next
- Note P261D 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 P261D
What does P261D mean?
P261D means "Coolant Pump B Control Circuit High". With P261D the module finds the drive of coolant pump B too high, either a short to the supply side or a current above the permitted limit. It is a generic code, so it means the same on every make.
Is it safe to drive with P261D?
Usually yes, for a short time, if the check engine light is steady and the car drives normally. If the light flashes or the car runs badly, stop and have it checked.
Will P261D fail an emissions test?
Yes, it can. P261D 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 P261D to fix?
Difficulty: medium. A typical repair takes 0.5 to 2.5 hours of work. A careful DIY repair is possible with basic tools and a scanner.
Will P261D clear itself after the repair?
Clear the code with a scanner after the repair. If the fault is fixed, it does not come back.
