TESTING 1.8L, 2.2L, 2.3L Engines



  1. Disconnect the negative battery cable.
  2.  
  3. Remove the black/yellow and white/blue wires from the terminals marked A (+) and B (-).
  4.  

Resistance will vary with coil temperature; therefore all specification were taken at an ambient temperature of 68°F (20°C)

  1. Measure the resistance between both terminals using an ohmmeter and compare with the following specifications:
    1. For the 1.8L engine, the primary winding resistance should be within 0.6-0.8 ohms. Proper secondary winding resistance is 12.8-19.2 kilohms.
    2.  
    3. For the 2.2L and 2.3L engines, the primary winding resistance should be 0.45-0.55 ohms. The secondary winding resistance should be 16.8-25.2 ohms.

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.  

2.5L Engine

  1. Disconnect the negative battery cable.
  2.  
  3. Remove the four prong connector.
  4.  
  5. Disconnect the ignition coil wire from the coil.
  6.  
  7. Use an ohmmeter to measure the resistance between the terminals as follows:
    1. Measure primary wire resistance between terminals 2 and 3. A result of 0.36-0.44 ohms is within specification.
    2.  
    3. Resistance between terminals 3 and 4 should be between 2.0-2.3 Kilohms.
    4.  

  8.  

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.  

3.0L Engine

  1. Disconnect the negative battery cable.
  2.  
  3. Remove the 3 prong connector from the ignition coil.
  4.  
  5. Remove the ignition coil wire.
  6.  
  7. Use an ohmmeter to measure the resistance between the terminals on the coil, and compare with the following:
    1. Resistance between the two outer most terminals should be between 0.34-0.42 ohms. This is the primary winding side of the coil.
    2.  
    3. The secondary winding resistance is found by measuring across the middle terminal of the coil and the secondary winding terminal. The resistance should be between 17.1-20.9 Kilohms.
    4.  

  8.  

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.

Fig. Fig. 7: Removal of the ignition coil from the Integra's 1.8L engine

  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.
  18.  

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.
