What P2C30 means
On engines whose ignition coils are fed through more than one fuse, the module checks each fuse so that it notices when a whole group of coils loses power. P2C30 points to fuse A. A GM patent explains the reasoning: coils and injectors sit on separate circuits, so after a fuse blows fuel would still be injected into cylinders without spark; the module therefore watches the current through the fuse over a sampling window and cuts the matching injectors to spare the exhaust system. Stellantis uses P2C30 on the 3.0L Hurricane twin-turbo I6 with a separate ignition system control module (ISCM): bulletins 08-205-24 (2025 Ram 1500) and 08-221-24 (2023 Wagoneer) fix it by ISCM software. Expect MIL, misfire and hesitation. Which cylinders fuse A serves is not published.
P2C30 at a glance
- Check engine lightYes, usually on
- Emissions testCan fail
- Limp modePossible
- Repair difficultyMedium
- Typical labor0.2 to 1.5 hours
- Clears after repairWhen cleared with a scanner
Symptoms of P2C30
- Check engine light
- Misfire on several cylinders, hesitation
- Reduced power while cylinders are shut off
Common causes of P2C30
- Most likelyIgnition system control module software (Stellantis 3.0L Hurricane)
- PossibleFuse A blown by a shorted ignition coil or supply wire
- Less likelyLoose or corroded fuse terminal
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of P2C30 means
| P | Powertrain system: engine, fuel system, ignition, emissions and transmission. |
| 2 | Generic code (second SAE range): it means the same on every make. |
| C | Area: hybrid propulsion. |
| 30 | The exact fault in that area. |
What to do next
- Note P2C30 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 P2C30
What does P2C30 mean?
P2C30 means "Ignition Coil Primary Circuit Fuse A". On engines whose ignition coils are fed through more than one fuse, the module checks each fuse so that it notices when a whole group of coils loses power. It is a generic code, so it means the same on every make.
Is it safe to drive with P2C30?
Drive gently and only to a workshop. With P2C30 the car can go into limp mode (reduced power) to protect itself.
Will P2C30 fail an emissions test?
Yes, it can. P2C30 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 P2C30 to fix?
Difficulty: medium. A typical repair takes 0.2 to 1.5 hours of work. This is a job for a workshop.
Will P2C30 clear itself after the repair?
Clear the code with a scanner after the repair. If the fault is fixed, it does not come back.
