What P2314 means
P2314 reports a fault on the high-voltage side of coil E, which only five-cylinder and larger engines have; it normally fires cylinder 5. The control line may be perfectly sound; what failed is the energy reaching the plug or the combustion that should follow. FCA is the documented user: on the 3.6-litre Pentastar V6 of 2015–2016 Caravan and Town & Country models it is coil 5 secondary circuit with insufficient ionization, one of six such codes that bulletin 18-069-16 tied to a faulty PCM in a short build window. GM, Ford and VW tables cover coil E only on the primary side (P2312, P2313, P0355). Practical checks are the plug of cylinder 5, the trunk and a swap test with a neighbouring coil; if the code stays with the cylinder, look at the plug or the module.
P2314 at a glance
- Check engine lightYes, usually on
- Emissions testCan fail
- Limp modePossible
- Repair difficultyMedium, DIY possible
- Typical labor0.3 to 3 hours
- Clears after repairAfter a drive cycle
Symptoms of P2314
- Check engine light on
- Misfire on cylinder 5
- Rough idle, slight vibration
Common causes of P2314
- Most likelySpark plug of cylinder 5 worn or fouled
- PossibleCoil E secondary winding or trunk damaged
- Less likelyPCM fault on FCA vans from the 2015 build window
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of P2314 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. |
| 14 | The exact fault in that area. |
What to do next
- Note P2314 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 P2314
What does P2314 mean?
P2314 means "Ignition Coil E Secondary Circuit". P2314 reports a fault on the high-voltage side of coil E, which only five-cylinder and larger engines have; it normally fires cylinder 5. It is a generic code, so it means the same on every make.
Is it safe to drive with P2314?
Drive gently and only to a workshop. With P2314 the car can go into limp mode (reduced power) to protect itself.
Will P2314 fail an emissions test?
Yes, it can. P2314 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 P2314 to fix?
Difficulty: medium. A typical repair takes 0.3 to 3 hours of work. A careful DIY repair is possible with basic tools and a scanner.
Will P2314 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.
