IGNITION COIL
Ignition coil resistance inspection
1.

Remove "IGNITION COIL".

2.

Measure the resistance between "Power" terminal and "Control" terminal of "IGNITION COIL".[1st coil resistance]

3.

Measure the resistance between "Power" terminal and "High-voltage" terminal of "IGNITION COIL".[2nd coil resistance]

■ Specification :

1st coil resistance

0.558 Ω ~ 0.682 Ω (20℃, 68℉)

2nd coil resistance

5.95 ㏀ ~ 8.05 ㏀ (20℃, 68℉)

4.

Are the 1st coil resistance and the 2nd coil resistance normal?

▶ Go to "1st ignition signal waveform inspection" procedure as below.

▶ Replace the ignition coil.
