Testing



2.2L (VIN 4) Engine
  1. Remove the ignition coil(s).
  2.  
  3. Using an ohmmeter, check the resistance between the primary terminals on the underside of the coil. The resistance should be 0.50-0.90 ohms.
  4.  
  5. Check the resistance between the secondary terminals. It should be 5000-10,000 ohms.
  6.  
  7. If the coil failed either test, replace the coil.
  8.  

2.4L (VIN T) Engines
  1. Remove the ignition coil(s).
  2.  
  3. Using an ohmmeter, check the resistance between the secondary terminals. Resistance should be 10,000 ohms.
  4.  
  5. If the coil secondary resistance is out of specification, replace the coil.
  6.
