What P25EE means
P25EE covers the second control circuit of an electric brake vacuum pump, the part of the wiring that should carry voltage while the pump is switched on. Ford's 2019 OBD summary for its hybrid and plug-in models assigns P25EE to the brake system module, mapped from that module's own code C1036: with the pump relay commanded closed, a monitoring line voltage below 250 mV for one second means the pump is not getting its supply, typically from an open circuit, a failed relay contact or a blown fuse. Circuit A (P258A) is judged with the relay open instead. On these vehicles the pump keeps the brake booster supplied when the combustion engine is shut down. P25EF to P25F1 are the performance, low and high codes of the same circuit. CARB treats such electrical outputs as comprehensive components. The pedal can turn hard.
P25EE at a glance
- Check engine lightYes, usually on
- Emissions testCan fail
- Limp modeNot expected
- Repair difficultyMedium, DIY possible
- Typical labor0.3 to 2.5 hours
- Clears after repairWhen cleared with a scanner
Symptoms of P25EE
- Hard brake pedal, especially with the engine off or in electric drive
- Brake or traction warning lamp in addition to the check engine lamp
- Vacuum pump never heard running
Common causes of P25EE
- Most likelyBlown vacuum pump fuse
- PossiblePump relay contact not closing
- PossibleBroken wire or loose connector between relay and pump
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of P25EE means
| P | Powertrain system: engine, fuel system, ignition, emissions and transmission. |
| 2 | Generic code (second SAE range): it means the same on every make. |
| 5 | Area: vehicle speed, idle control and auxiliary inputs. |
| EE | The exact fault in that area. |
What to do next
- Note P25EE 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 P25EE
What does P25EE mean?
P25EE means "Vacuum Pump Control Circuit B/Open". P25EE covers the second control circuit of an electric brake vacuum pump, the part of the wiring that should carry voltage while the pump is switched on. It is a generic code, so it means the same on every make.
Is it safe to drive with P25EE?
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 P25EE fail an emissions test?
Yes, it can. P25EE 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 P25EE to fix?
Difficulty: medium. A typical repair takes 0.3 to 2.5 hours of work. A careful DIY repair is possible with basic tools and a scanner.
Will P25EE clear itself after the repair?
Clear the code with a scanner after the repair. If the fault is fixed, it does not come back.
