P2332 Ignition Coil K Secondary Circuit

P2332 reserves a code for trouble between coil K and the plug of cylinder 11. No manufacturer documents it publicly: the only published secondary-circuit series, FCA's ion-current codes, covers coils 1 to 8, and twelve-cylinder makers do not release their code lists. Ion-current sensing, known from Saab's Direct Ignition, would be one way to detect such a fault; another is evaluating the secondary voltage. On a V12 with coil-on-plug, the high-voltage path is short – coil tower, boot, plug – so the usual faults are a perforated boot, oil in the plug well or an eroded plug. Whatever the source, CARB still demands cylinder-specific misfire detection, so P0311 is the more likely code to appear. P2330/P2331 cover the primary wiring of the same coil.

Likely causes

Coil K boot perforated
Oil in the plug well of cylinder 11
Spark plug of cylinder 11 worn out

Symptoms

  • Check engine light on
  • Misfire on cylinder 11 (P0311)
  • Faint vibration at idle
