What P2625 means
With P2625 the module sees the injection pressure regulator circuit at too high a level: the switched line is shorted to battery voltage, or the IPR coil draws more current than the driver allows. No manufacturer documents this code publicly; Ford's 6.0 L Power Stroke summaries from 2003 to 2009 fold every IPR driver fault into P2623, and International's HEUI truck engines report through their own codes. The regulator matters because it alone decides how much oil pressure reaches the injectors; Navistar's HEUI design lets that pressure be set independently of engine speed. If the PCM cannot pull the IPR coil, rail pressure stays near minimum, so the engine may not start at all. CARB treats such hydraulic pressure control as part of fuel system monitoring.
P2625 at a glance
- Check engine lightYes, usually on
- Emissions testCan fail
- Limp modePossible
- Repair difficultyHard
- Typical labor0.5 to 4 hours
- Clears after repairWhen cleared with a scanner
Symptoms of P2625
- Long cranking or no-start
- Low power, engine may stall
- Malfunction indicator lamp on
Common causes of P2625
- Most likelyIPR control line shorted to a battery-voltage circuit
- PossibleIPR coil with reduced resistance causing overcurrent
- Less likelyFaulty IPR driver in the PCM
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of P2625 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. |
| 25 | The exact fault in that area. |
What to do next
- Note P2625 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 P2625
What does P2625 mean?
P2625 means "Injector Control Pressure Regulator Circuit High". With P2625 the module sees the injection pressure regulator circuit at too high a level: the switched line is shorted to battery voltage, or the IPR coil draws more current than the driver allows. It is a generic code, so it means the same on every make.
Is it safe to drive with P2625?
Drive gently and only to a workshop. With P2625 the car can go into limp mode (reduced power) to protect itself.
Will P2625 fail an emissions test?
Yes, it can. P2625 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 P2625 to fix?
Difficulty: hard. A typical repair takes 0.5 to 4 hours of work. This is a job for a workshop.
Will P2625 clear itself after the repair?
Clear the code with a scanner after the repair. If the fault is fixed, it does not come back.
