Ignition Coil: Inspection: Procedure

  1. INSPECT IGNITION COIL 
    1. Perform the spark test and identify the malfunctioning cylinder.

      Refer to ON-VEHICLE INSPECTION

    2. Replace the ignition coil of the malfunctioning cylinder with that of a normal cylinder, and perform the spark test again.

      Refer to ON-VEHICLE INSPECTION

      • If the spark is not normal due to a malfunctioning ignition coil, replace that ignition coil.

        Refer to REMOVAL 

      • It is unlikely that all four ignition coils fail to operate properly. To prevent replacing a normal component, perform the above procedure, identify the malfunctioning ignition coil, and replace it.
