Testing



3.5L Engine
Ignition Coil Test
  1. Remove the ignition coil.
  2.  
  3. Measure the primary coil resistance, as follows:
    1. Connect the negative (-) terminal of a 3V power supply to terminal 2 of the power transistor. Check to see if there is continuity between terminals 3 and 2 when terminal 1 and the positive (+) terminal are connected and disconnected.
    2.  
    3. When they are connected, the continuity should be 0.78 ohms plus or minus 10%.
    4.  
    5. When they are disconnected, there should not be continuity.

  4.  
  5. Measure secondary coil resistance making the connections as shown and measuring the resistance between the high-voltage terminals of the ignition coil. There should be 11.4-15.6 ohms of resistance.

Spark Test
  1. Disconnect the negative battery cable.
  2.  
  3. Remove the engine cover.
  4.  
  5. Detach the ignition coil connector from the ignition coil. To remove the ignition coil connector, pull the lock pin, then push the clip.

  9. Remove the ignition coil from the engine.
  10.  
  11. Using a spark plug socket, remove the spark plug.
  12.  
  13. Attach the spark plug to the ignition coil.
  14.  
  15. Reconnect the ignition coil harness connector to the ignition coil.
  16.  
  17. Ground the spark plug to the engine.
