P2335 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. 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 boot 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.

Likely causes

Symptoms

• Check engine light on, possibly flashing with heavy misfire
• Misfire on cylinder 12 (P0312)

Repair estimate

Typical range across vehicles; the real cost depends on what the testing finds.
