Ignition Coil Inspection

  1. Perform the spark inspection and identify the malfunctioning cylinder. (See SPARK INSPECTION .)
  2. Replace the ignition coil/ion sensor of the malfunctioning cylinder with that of a normal cylinder, and perform the spark inspection again. (See SPARK INSPECTION .)
    • If the spark is not normal due to a malfunctioning ignition coil/ion sensor, replace that ignition coil/ion sensor.
    • It is unlikely that all four ignition coil/ion sensors fail to operate properly. To prevent replacing a normal component, perform the above procedure, identify the malfunctioning ignition coil/ion sensor, and replace it.
