What P26CE means
P26CE covers a pump that spins too fast for the current it draws – a sign that it is running dry or pumping air instead of coolant. Ford's hybrid OBD summaries spell out the check: the electronics in the pump report a dry-run state over LIN when speed exceeds 4,909 rpm while current stays too low, and the PCM sets the code after five seconds. Toyota lists P26CE with a 37 suffix among the A25A codes in Tech Tip T-TT-0714-22 for 2022–2023 hybrids and gasoline models. Mercedes-Benz names it in information LI20.00-P-071399 for M256 engines built 07/2019 to 02/2020, together with a coolant temperature warning, and asks to check for leaks and trapped air. Unlike P26CB the pump is free to turn here, but coolant is missing around it, so the level should be checked first.
P26CE at a glance
- Check engine lightYes, usually on
- Emissions testCan fail
- Limp modePossible
- Repair difficultyMedium, DIY possible
- Typical labor0.5 to 3 hours
- Clears after repairWhen cleared with a scanner
Symptoms of P26CE
- Coolant temperature warning in the cluster
- Check engine lamp on
- Gurgling noises or poor heater output
Common causes of P26CE
- Most likelyLow coolant level from a leak
- PossibleAir pockets left after coolant service or pump replacement
- Less likelyImpeller loose or broken on the pump shaft
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of P26CE 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. |
| CE | The exact fault in that area. |
What to do next
- Note P26CE 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 P26CE
What does P26CE mean?
P26CE means "Engine Coolant Pump Overspeed/Air In System". P26CE covers a pump that spins too fast for the current it draws – a sign that it is running dry or pumping air instead of coolant. It is a generic code, so it means the same on every make.
Is it safe to drive with P26CE?
Drive gently and only to a workshop. With P26CE the car can go into limp mode (reduced power) to protect itself.
Will P26CE fail an emissions test?
Yes, it can. P26CE 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 P26CE to fix?
Difficulty: medium. A typical repair takes 0.5 to 3 hours of work. A careful DIY repair is possible with basic tools and a scanner.
Will P26CE clear itself after the repair?
Clear the code with a scanner after the repair. If the fault is fixed, it does not come back.
