Ignition Coil: Testing and Inspection

Primary Coil Resistance:

Primary Coil Resistance
Measure the resistance between connector terminal (3) (power) and each coil terminal.
Measuring point:
Coil A (No. 1 - No. 4 cylinder side coil) (2) - (3)
Coil B (No. 2 - No. 5 cylinder side coil) (1) - (3)
Coil C (No. 3 - No. 6 cylinder side coil) (4) - (3)
Standard value: 0.67 - 0.81 Ohm

Secondary Coil Resistance:

Secondary Coil Resistance
Measure the resistance between each coil high voltage terminals.
Measuring point:
Coil A (No. 1 - No. 4 cylinder side coil)
Coil B (No. 2 - No. 5 cylinder side coil)
Coil C (No. 3 - No. 6 cylinder side coil)
Standard value: 11.3 - 15.3 K-Ohm.
