Ignition System Inspection

1. Visually/physically inspect the spark plug cable and ignition coil related to the misfiring cylinder(s) for the following conditions
   • Damage, cracks, carbon and flashover
   • Poor connection or damaged harness
   • Connected to the incorrect cylinders at the ignition coil and spark plug
2. Measure the resistance of the spark plug cable related to the misfiring cylinder(s)

   Specification  : 5.6kΩ/m ±20%

3. Measure the resistance of the primary and secondary ignition coil related to the misfiring cylinder(s)

   Specification  : Primary Ignition Coil Resistance : Approx. 0.5~0.6Ω at 20°C(68°F)

   Secondary Ignition Coil Resistance : Approx. 7.5~10.2kΩ at 20°C(68°F)

4. Was a problem found in any of the above areas?

   YES 

   • Repair or replace as necessary and go to "VERIFICATION OF VEHICLE REPAIR " procedure

   NO 

   • Go to next step as below

1. Visually/physically inspect the spark plug related to the misfiring cylinder(s) for the following conditions
   • Damaged insulation, Worn electrodes, Oil or fuel fouled, Loose terminals and cracks
   • Check for electrode gap : 1.0 - 1.1 mm (0.039 - 0.043 in.)
   • Check if the spark plug for the relevant cylinder is lighter in color than the other plugs.
2. Was a problem found in any of the above areas?

YES 

• Replace or adjust as necessary and go to "VERIFICATION OF VEHICLE REPAIR " procedure

NO 

• Go to next step as below
