  1. Disconnect the negative battery cable.
  2.  
  3. Remove the distributor cap, as outlined in Section 1 of this guide.
  4.  
  5. Remove the black/yellow and white/black wires from the terminals marked A (+) and B (-).
  6.  

Resistance will vary with coil temperature; therefore all specifications 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. The primary winding resistance should be 0.45-0.55 ohms
    2.  
    3. The secondary winding resistance should be 16.8-25.2 ohms.
    4.  

  2.  

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.

  1. Disconnect the negative battery cable.
  2.  

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

  1. Remove the distributor cap, as outlined in Section 1.
  2.  
  3. Detach the 4-prong connector and igniter wire.
  4.  
  5. Measure the resistance between the terminals and replace the coil if the specifications differ from the following:
    1. The primary winding resistance (measurement between A and B) should be between 0.64-0.78 ohms.
    2.  
    3. The secondary winding resistance (measurement between A and the secondary winding terminal) should be between 14.4-21.6 kilohms.
    4.  

  6.  

PRELUDE
  1. Turn the ignition switch OFF .
  2.

  1. Using an ohmmeter, measure the primary winding resistance between terminals A and C. The resistance should be 0.64-0.78 ohms. If not, replace the ignition coil.
  2.  
  3. Using an ohmmeter, measure the secondary winding resistance between terminal A and the secondary winding terminal. The resistance should be 14.4-21.6 kilohms. If not, replace the ignition coil.
  4.  
  5. Check for continuity between the terminals A and B. If there is no continuity, replace the coil.
  6.  

2.3L Engine
  1. Disconnect the negative battery cable.
  2.  

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

  1. Remove the distributor cap, as outlined in Section 1.
  2.  
  3. Detach the wires from the terminals of the coil.
  4.  
  5. Measure the resistance between the coil terminals.
  6.  
  7. Replace the coil if the measurements taken do not fall within the following specifications:

    Primary winding resistance (F23A1, F23A4 engines): 0.45-0.55 ohms.
     
    Primary winding resistance (F23A5 engine): 0.63-0.77 ohms.
     
    Secondary winding resistance (F23A1, F23A4 engines): 16.8-25.2 kilohms.
     
    Secondary winding resistance (F23A5 engine): 12.8-19.2 kilohms.

  3. Remove the distributor cap, as outlined in Section 1.
  4.  
  5. Unplug the 4-prong connector from the ignition coil.
  6.  
  7. Remove the ignition coil wire.
  8.  
  9. Use an ohmmeter to measure the resistance between the terminals on the coil, and compare with the following:
    1. Measure the primary winding resistance, between the A and C terminals, and replace the coil if the resistance is not between 0.3-0.4 ohms.
    2.  
    3. Measure the secondary winding resistance, between the B and D terminals, and replace the coil if the resistance is not between 14-22 kilohms.

  1. Disconnect the negative battery cable.
  2.  
  3. Remove the distributor cap, as outlined in Section 1.
  4.  
  5. Unplug the 3-prong connector from the ignition coil.
  6.  
  7. Remove the ignition coil wire.
  8.  
  9. 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 (#1 and #3) 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 (#2) of the coil and the secondary winding terminal. The resistance should be between 17.1-20.9 kilohms.
    4.  

  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.

  1. Reconnect the negative battery cable.
