CHECK IGNITION COIL ASSEMBLY AND PERFORM SPARK TEST

1. Check for DTCs.

   Note

   If any DTC is present, perform troubleshooting in accordance with the procedure for that DTC.

2. Check that sparks occur.

   
   

   1. Remove the ignition coils.

   2. Using a 16 mm plug wrench, remove the spark plugs.

   3. Install the spark plugs to each ignition coil, and connect the ignition coil connectors.

   4. Disconnect the 6 injector connectors.

   5. Ground the spark plugs.

   6. Check if sparks occur at each spark plug while the engine is being cranked.

      Note

      
      

      • Be sure to ground the spark plug when checking.

      
      

      • Replace the ignition coil if it receives an impact.

      
      

      • Do not crank the engine for more than 2 seconds.

      Tech Tips

      
      

      • If spark occur, skip the spark test flowchart.

      
      

      • If sparks do not occur, proceed to the spark test flowchart.

3. Spark test flowchart.

   
   

   1. Check that the wire harness side connector of the ignition coil with igniter is securely connected.

      Result
      Result Proceed to NG Connect securely OK Go to next step

   2. Perform spark test on each ignition coil with igniter.

      1. Replace ignition coil with igniter with a normal one.

      2. Perform spark test again.

      Result
      Result Proceed to OK Replace ignition coil with igniter NG Go to next step

   3. Check power supply to the ignition coil.

      1. Turn the ignition switch ON.

      2. Check that there is battery positive (+) voltage at the ignition coil positive (+) terminal.

      Result
      Result Proceed to NG Check wiring between ignition switch and ignition coil assembly OK Go to next step

   4. Check the resistance of the VVT sensor output voltage (see step Click here).

      Result
      Result Proceed to NG Follow test 1 OK Go to next step

      1. Check the wiring between the VVT sensor and ECM.

      Result
      Result Proceed to NG Repair wiring between VVT sensor and ECM OK Replace VVT sensor

   5. Check the resistance of the crankshaft position sensor.

      Standard resistance
      Standard Condition Specified Condition Cold 1.630 to 2.740 Ω Hot 2.065 to 3.225 Ω

      Result
      Result Proceed to NG Replace the crankshaft position sensor OK Go to next step

   6. Check IGT signal from the ECM Click here.

      Result
      Result Proceed to NG Check ECM Click here OK Repair wiring between ignition coil and ECM

4. Using a 16 mm plug wrench, install the spark plugs.

   Torque:

   20 N*m  { 204 kgf*cm, 13 ft.*lbf }

5. Install the ignition coils.

   Torque:

   9.0 N*m  { 92 kgf*cm, 80 in.*lbf }
