Ignition Coil: Testing and Inspection

IGNITION COILS

CHECKING IGNITION COILS




1. Measure the primary coil resistance between terminals 1 and 2 of connectors C18-2 and C68-1 (the coils at the No.1 and No.4 cylinder sides) of the ignition coil, and between terminals 1 and 2 of connectors C18-1 and C68-2 (the coils at the No.2 and No.3 cylinder sides).

Standard value : 0.5 ± 0.05 k ohm




2. Measure the secondary coil 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 : 12.1 ± 1.8 k ohm

CAUTION: When measuring the resistance of the secondary coil, be sure to disconnect the ignition coil connector.
