What P2317 means
P2317 concerns the high-voltage side of coil F, which serves cylinder 6 on engines with six or more cylinders. With coil-on-plug designs there is no separate lead any more – Ford notes that individual coils did away with plug wires – so a secondary fault lies in the coil, its trunk or the plug. FCA's 3.6 Pentastar V6 is the documented user: P2317, coil 6 secondary circuit with insufficient ionization, is the last of the six ion-sense codes in bulletin 18-069-16 for 2015–2016 Caravan and Town & Country. The principle comes from systems such as Saab's Direct Ignition, which measure ion current across the plug to recognise misfire and knock. Ford, GM and VW record coil F only on the primary side; a weak spark there appears as P0306.
P2317 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 P2317
- Check engine light on
- Misfire on cylinder 6
- Uneven running, especially under load
Common causes of P2317
- Most likelySpark plug of cylinder 6 worn or wrongly gapped
- PossibleCoil F trunk cracked or contaminated
- PossibleCoil F secondary winding failing
- Less likelyPCM ion-current evaluation defective (FCA)
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of P2317 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. |
| 17 | The exact fault in that area. |
What to do next
- Note P2317 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 P2317
What does P2317 mean?
P2317 means "Ignition Coil F Secondary Circuit". P2317 concerns the high-voltage side of coil F, which serves cylinder 6 on engines with six or more cylinders. It is a generic code, so it means the same on every make.
Is it safe to drive with P2317?
Drive gently and only to a workshop. With P2317 the car can go into limp mode (reduced power) to protect itself.
Will P2317 fail an emissions test?
Yes, it can. P2317 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 P2317 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 P2317 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.
