Installation

Do not confuse ignition coil #2 with connector #4. This may cause the engine to stop due to incomplete combustion. Also, since unburned fuel enters the catalytic converter, this may cause overheating and damage to the catalytic converter. The yellow tag (A) is attached to ignition coil #4. Use this tag as a reference when connecting the ignition coils.
  1. Install in the reverse order of removal. Ignition coil bolts: 9.8 ~ 11.8 N·m

Inspection

  1. Measure the primary coil resistance between terminals (+) and (-).

    Standard value: 0.62 Ω ± 10%
