Testing



Specific to:

Toyota Avalon 1995-1996

  1. Remove the spark plug wires from the ignition coil pack that you are going to test.
  2.  
  3. Detach the primary wiring connector from the ignition coil.
  4.  
  5. Using an ohmmeter, measure the resistance between the positive and negative terminals on the primary side of the ignition coil pack. The resistance should be between 0.70-0.94 Ohms if the coil pack is cold. If hot (normal operating temperature of the engine) when tested, the resistance between the terminals should be between 0.85-1.10 Ohms.

    Fig. Using an ohmmeter, measure the resistance between the terminals of the primary side of the ignition coil.

  6.  
  7. If the resistance is not within the specified range, replace the ignition coil. If the resistance is within the specified range, conduct the secondary coil resistance test.
  8.  
  9. Again using an ohmmeter, measure the resistance between the positive and the high-tension terminal. The resistance should be between 10.8-14.9 kilo-ohms when cold. If the ignition coil is hot, the resistance should be between 13.1-17.5 kilo-ohms. If the resistance is not within the specified range, replace the ignition coil.
