What P2324 means
Coil I is the ninth coil, so P2324 only appears on ten- or twelve-cylinder gasoline engines. The documented user is Ford: its OBD system summaries (2012 and 2020–2023) group P2324 with the other codes for a coil driver shorted to ground, monitored continuously from 200 rpm with the battery between 11 and 16 V, and Ford's 2014 code interpretation list marks it as a MIL code. The candidate engine in Ford's range is the 6.8-litre Modular V10 of the E-Series and heavy trucks, for which Ford also specifies a 40-1 crank wheel. After a driver fault the PCM shuts the injector of that cylinder for 30 s and retries. GM's tables end at coil H, so no GM engine uses this code. Opens on coil I are P0359, misfire on cylinder 9 is P0309.

Symptoms of P2324
- Check engine light on
- Cylinder 9 cuts out, rough running
- Reduced towing or climbing power
Common causes of P2324
- Most likelyCoil I (cylinder 9) shorted internally
- PossibleCoil I control wire grounded on the engine or exhaust side
- PossibleMoisture or corroded pins at the coil I plug
- Less likelyPCM coil driver for cylinder 9 failed
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of P2324 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. |
| 24 | The exact fault in that area. |
What to do next
- Note P2324 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 P2324
What does P2324 mean?
P2324 means "Ignition Coil I Primary Control Circuit Low". Coil I is the ninth coil, so P2324 only appears on ten- or twelve-cylinder gasoline engines. It is a generic code, so it means the same on every make.
Is it safe to drive with P2324?
Drive gently and only to a workshop. With P2324 the car can go into limp mode (reduced power) to protect itself.
Will P2324 fail an emissions test?
Yes, it can. P2324 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 P2324 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 P2324 clear itself after the repair?
Clear the code with a scanner after the repair. If the fault is fixed, it does not come back.
