Removal & Installation



1.8L Engines
  1. Disconnect the negative battery cable.
  2.  
  3. Remove the distributor cap.
  4.  
  5. Mark the position of the rotor to the housing.
  6.  
  7. Remove the ignition rotor.
  8.  
  9. Remove the cap seal.
  10.  
  11. Remove the leak cover.
  12.  
  13. Remove the screws that hold the black/yellow and white/blue wires to the ignition coil.
  14.  
  15. Unfasten the screws that secure the coil, then pull the ignition coil from the housing.
  16.  
  17. Installation is the reverse of the removal procedure.
    NOTE
    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.

Testing



1.8L Engines
  1. Disconnect the negative battery cable.
  2.  
  3. Remove the black/yellow and white/blue wires from the terminals marked A (+) and B (-).
    NOTE
    Resistance will vary with coil temperature; therefore all specification were taken at an ambient temperature of 68°F (20°C)

  4.  
  5. Measure the resistance between both terminals using an ohmmeter and compare with the following specifications:
    1. The primary winding resistance should be within 0.6-0.8 ohms. Proper secondary winding resistance is 12.8-19.2 kilohms.
      NOTE
      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.
