What P2322 means
P2322 is the counterpart to P2321: the coil H control line, cylinder 8 on most V8 layouts, reads as if it were tied to voltage. GM monitors it the same way on the 2019 LT5 and L84 engines, as a Type B code, flagged once 50 of 63 samples fail. Ford names P2322 in two special service messages from 2024: SSM 52455 for 6.8 and 7.3-litre gasoline trucks (Super Duty, F-53/F-59, E-Series, F-650/750) and SSM 52342 for the Bronco. Both say the PCM may file the code under the wrong cylinder and will cut fuel to the cylinder it blames; a power balance test shows the cylinder that genuinely drops out. Ford's OBD summaries add that fuel to the affected cylinder stays off for 30 s and is cut again as soon as the fault reappears. GM PIP5147 also covers P2322 on 2014 trucks.
P2322 at a glance
- Check engine lightYes, usually on
- Emissions testCan fail
- Limp modePossible
- Repair difficultyMedium, DIY possible
- Typical labor0.3 to 2.5 hours
- Clears after repairAfter a drive cycle
Symptoms of P2322
- Check engine light on
- One cylinder repeatedly shut off for about 30 s (Ford)
- Noticeable vibration and loss of power
Common causes of P2322
- Most likelyCoil H control wire shorted to a voltage-carrying line
- PossibleCoil H defective internally
- Less likelyPCM assigns the code to the wrong cylinder (Ford SSM 52455/52342)
- Less likelyOutput stage in the engine module faulty
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of P2322 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. |
| 22 | The exact fault in that area. |
What to do next
- Note P2322 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 P2322
What does P2322 mean?
P2322 means "Ignition Coil H Primary Control Circuit High". P2322 is the counterpart to P2321: the coil H control line, cylinder 8 on most V8 layouts, reads as if it were tied to voltage. It is a generic code, so it means the same on every make.
Is it safe to drive with P2322?
Drive gently and only to a workshop. With P2322 the car can go into limp mode (reduced power) to protect itself.
Will P2322 fail an emissions test?
Yes, it can. P2322 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 P2322 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 P2322 clear itself after the repair?
After the repair the car has to complete a drive cycle (a mix of city and highway driving) before the test runs again. Until then the readiness monitor shows "not ready", which can fail an inspection.
