Testing



2.0L Engine
Ignition Coil Primary Resistance Check
  1. Using an ohmmeter, check primary coil resistance as follows:
    1. Disconnect the electrical connector at the coil assembly.
    2.  
    3. At the coil side of the connector, measure the resistance between terminals 1-2.
    4.  
    5. At the coil side of the connector, measure the resistance between terminals 1-3.
    6.  
    7. Primary coil resistance for both measurements should be between 0.52-0.63 ohms at 68°F (20°C)
    8.  
    9. If not within specification, replace coil assembly.

Ignition Coil Secondary Resistance Check
  1. Using an ohmmeter, check coil secondary resistance as follows:
    WARNING
    When measuring the resistance of the secondary coil, make certain to disconnect the connector at the ignition coil.

    1. Measure the secondary coil resistance between the high-voltage terminal for the No.1 and No.4 cylinders.
    2.  
    3. Measure the secondary coil resistance between the high-voltage terminal for the No.2 and No.3 cylinders.
    4.  
    5. Secondary coil resistance for both measurements should be between 7.5-10k ohms at 68°F (20°C)
    6.  
    7. If not within specification, replace the coil assembly.

2.7L Engine
Ignition Coil Primary Resistance Check
  1. Using an ohmmeter, check primary coil resistance as follows:
    1. Disconnect the electrical connector at the coil assembly.
    2.  
    3. At the coil side of the connector, measure the resistance between terminals 1-4.
    4.  
    5. At the coil side of the connector, measure the resistance between terminals 2-4.
    6.  
    7. At the coil side of the connector, measure the resistance between terminals 3-4.
    8.  
    9. Primary coil resistance for all measurements should be between 0.86-1.05 ohms at 68°F (20°C)
    10.  
    11. If not within specification, replace coil assembly.

Ignition Coil Secondary Resistance Check
  1. Using an ohmmeter, check coil secondary resistance as follows:
    WARNING
    When measuring the resistance of the secondary coil, make certain to disconnect the connector at the ignition coil.

    1. Measure the secondary coil resistance between the high-voltage terminal for the No.1 and No.4 cylinders.
    2.  
    3. Measure the secondary coil resistance between the high-voltage terminal for the No.2 and No.5 cylinders.
    4.  
    5. Measure the secondary coil resistance between the high-voltage terminal for the No.3 and No.6 cylinders.
    6.  
    7. Secondary coil resistance for all measurements should be between 10.6-14.5k ohms at 68°F (20°C)
    8.  
    9. If not within specification, replace the coil assembly.

Removal & Installation




WARNING
Always install the spark plug wires in the same location, position and routing as they were in during removal.

  1. Disconnect the negative battery cable.
  2.  
  3. If equipped, remove the engine cover.
    NOTE
    When removing the spark plug cable, pull on the spark plug cable boot (not the cable), as it may be damaged.

  4.  
  5. Tag and disconnect the spark plug wires from the ignition coils.
  6.  
  7. Remove the fasteners securing the coil assembly to the engine and remove the coil assembly.
  8.  

To install:

  1. Install the coil assembly to the engine and secure with the fasteners.
  2.  
  3. Connect the spark plug wires to the ignition coil, as tagged during removal.
  4.  
  5. If removed, reinstall the engine cover.
  6.  
  7. Reconnect the negative battery cable.
