Ignition Coil Resistance (Civic)

Turn ignition off. Remove distributor cap. Remove 2 Phillips screws retaining primary ignition leads to ignition coil. Remove primary leads from ignition coil. Using an ohmmeter, check resistance between primary terminals "A" and "B" on ignition coil. See Fig 1 . Resistance should be .6-.8 ohm at room temperature.

Check secondary resistance between terminal "A" and secondary output terminal (coil tower) at room temperature. See IGNITION COIL RESISTANCE table. If readings are not within specification, replace coil.
