Component Inspection

1. Turn ignition switch to OFF and disconnect ignition coil connector.
2. Check ignition coil and plug wires for cracks or carbon tracing.
3. Check resistance of primary coil.

   Specification: Primary coil resistance: 0.87Ω +/- 10%

4. Check resistance of secondary coil.

   Specification: Secondary coils resistance: 13.0^kΩ +/- 15%

5. Check for resistance of plug wires.

   Specification: Plug wire: 5.6 ^kΩ /m +/- 20%

6. Is the resistance of ignition coils and plug wires within specification?

   YES 

   • Go to "Check for spark plug" below.

   NO 

   • Faulty ignition coils or plug wires.
   • Repair as necessary and go to "VERIFICATION OF VEHICLE REPAIR " procedure.

Check the following items below for spark plug.

1. Remove spark plugs and check gap and plug condition.
2. Check the electrode condition (wear or carbon deposit)
3. Check the insulators condition (crack, etc)
4. Check the carbon deposit

   Specification: gap: 1.0~1.1mm

5. Are spark plugs gapped properly and in good condition?

   YES 

   • Go to "Check for vacuum and PCV" below.

   NO 

   • Faulty spark plugs.
   • Repair as necessary and go to "VERIFICATION OF VEHICLE REPAIR " procedure.

Check for any split, disconnected or perforated vacuum hoses. Also, check PCV valve for proper operation.

1. Remove the positive crankcase ventilation valve.
2. Insert a thin stick into the positive crankcase ventilation valve from the threaded side to check that the plunger moves.
3. If the plunger does not move, the positive crankcase ventilation valve is clogged. Clean or replace it.

4. Are vacuum hoses and PCV okay?

   YES 

   • Go to "SYSTEM INSPECTION " procedure.

   NO 

   • Replace faulty vacuum hoses or PCV.
   • Repair as necessary and go to "VERIFICATION OF VEHICLE REPAIR " procedure.
