Fig. Fig. 1: Checking the ignition coil on a 3.2L engine

  1. Disconnect the negative battery cable.
  2.  
  3. Remove the ignition coil.
  4.  

In order to get to the ignition coil at the No. 6 cylinder, it may be necessary to remove the A/C suction line mounting bolts to enable the line to be moved over slightly. This will provide adequate access to the coil.

  1. Remove the two wire connector that feeds the coil battery voltage.
  2.  
  3. Use an ohmmeter to check the primary coil resistance between the two terminals on the coil. Resistance should be between 0.9-1.1 ohms.
  4.  

The Powertrain Control Module (PCM) idle memory must be reset after reconnecting the battery. Start the engine and hold it at 3000 rpm until the cooling fan comes on. Then allow the engine to idle for about five minutes with all accessories OFF and with the transmission in Park or Neutral.

  1. Reconnect the negative battery cable.
  2.

Fig. Fig. 2: Test the ignition coil by measuring resistance between terminals 1 & 2-3.5L engine

  1. Disconnect the negative battery cable.
  2.  
  3. Remove the strut brace by unscrewing the 4 nuts and one bolt.
  4.  
  5. Remove the engine cover.
  6.  
  7. Remove the ignition coil.
  8.  
  9. Measure the resistance of the coil between terminals 1 and 2. Primary winding resistance should be between 0.9-1.1 ohms.
  10.  

The Powertrain Control Module (PCM) idle memory must be reset after reconnecting the battery. Start the engine and hold it at 3000 rpm until the cooling fan comes on. Then allow the engine to idle for about five minutes with all accessories OFF and with the transmission in Park or Neutral.

  4.  
  5. Remove the ignition coil wire.
  6.  
  7. Remove the ignition coil by removing the mounting bolts.
  8.  
  9. Remove the ignition coil.
  10.  
  11. Install is the reverse of the removal procedure.
  12.  

The Powertrain Control Module (PCM) idle memory must be reset after reconnecting the battery. Start the engine and hold it at 3000 rpm until the cooling fan comes on. Then allow the engine to idle for about five minutes with all accessories OFF and with the transmission in Park or Neutral.
