What P2325 means
P2325 flags a short to voltage on the trigger line of coil I, the ninth ignition output. Ford is again the only maker that lists it publicly: in its OBD summaries P2325 sits among the codes for a coil driver shorted high, and the 2014 Ford code list shows it as a MIL-lighting code checked with the engine running. The PCM judges current and voltage on the driver against open and short limits; when it trips, it stops fuel to that cylinder to protect the catalyst, waits 30 s and turns the injector back on, repeating the cut within about 0.1 s if the fault is still there. That makes the symptom a pulsing loss of one cylinder rather than a steady miss. On a Ford V10 the cause is mostly the coil or a chafed wire; P2324 is the ground-side fault on the same coil.

Symptoms of P2325
- Check engine light on
- Cylinder 9 drops out in roughly 30 s cycles
- Uneven idle and vibration
Common causes of P2325

Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of P2325 means
| P | Powertrain system: engine, fuel system, ignition, emissions and transmission. |
| 2 | Generic code (second SAE range): it means the same on every make. |
| 3 | Area: ignition system or misfire. |
| 25 | The exact fault in that area. |
What to do next
- Note P2325 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 P2325
What does P2325 mean?
P2325 means "Ignition Coil I Primary Control Circuit High". P2325 flags a short to voltage on the trigger line of coil I, the ninth ignition output. It is a generic code, so it means the same on every make.
Is it safe to drive with P2325?
Drive gently and only to a workshop. With P2325 the car can go into limp mode (reduced power) to protect itself.
Will P2325 fail an emissions test?
Yes, it can. P2325 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 P2325 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 P2325 clear itself after the repair?
Clear the code with a scanner after the repair. If the fault is fixed, it does not come back.
