Ignition Coil: Testing and Inspection

Measurement of the primary coil resistance





1. Measure the resistance between connector terminals 3 and 1 (the coils at the No. 1 and No. 4 cylinder sides) of the ignition coil, and between terminals 3 and 2 (the coils at the No. 2 and No. 3 cylinder sides).

Standard value: 0.77 - 0.95 ohms

Measurement of the secondary coil resistance





1. Measure the resistance between the high-voltage terminal for the No. 1 and No. 4 cylinders, and between the high-voltage terminals for the No. 2 and No. 3 cylinders.

Standard value: 10.3 - 13.9 K ohms

CAUTION: Be sure, when measuring the resistance of the secondary coil, to disconnect the connector of the ignition coil.
