What P2335 means
P2335 closes the ignition coil block of J2012: a fault on the high-voltage side of coil L, the twelfth coil. No manufacturer documents this code publicly, and none of the reviewed ion-sensing or secondary-monitoring documents reaches past coil 8. Its practical relevance is therefore small; a V12 with a failing coil L, a cracked trunk or a worn plug on the last cylinder will normally report it as misfire on cylinder 12 (P0312), and with catalyst-damaging misfire CARB rules require the MIL to flash. If the code does appear, swap coil and plug with another cylinder of the same bank and see whether the fault follows. P2333/P2334 belong to the primary circuit of the same coil; P2332 is the neighbouring coil K secondary code.
P2335 at a glance
- Check engine lightYes, usually on
- Emissions testCan fail
- Limp modeNot expected
- Repair difficultyHard
- Typical labor0.5 to 4 hours
- Clears after repairAfter a drive cycle
Symptoms of P2335
- Check engine light on, possibly flashing with heavy misfire
- Misfire on cylinder 12 (P0312)
Common causes of P2335
- Most likelySpark plug of cylinder 12 worn
- PossibleCoil L trunk cracked
- PossibleCoil L secondary winding weak
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of P2335 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. |
| 35 | The exact fault in that area. |
What to do next
- Note P2335 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 P2335
What does P2335 mean?
P2335 means "Ignition Coil L Secondary Circuit". P2335 closes the ignition coil block of J2012: a fault on the high-voltage side of coil L, the twelfth coil. It is a generic code, so it means the same on every make.
Is it safe to drive with P2335?
Usually yes, for a short time, if the check engine light is steady and the car drives normally. If the light flashes or the car runs badly, stop and have it checked.
Will P2335 fail an emissions test?
Yes, it can. P2335 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 P2335 to fix?
Difficulty: hard. A typical repair takes 0.5 to 4 hours of work. This is a job for a workshop.
Will P2335 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.
