Ignition Coil: Testing and Inspection
1. INSPECT IGNITOR AND SPARK TESTCheck that the spark occurs.
1. Disconnect high-tension cords from spark plug.
2. Remove the spark plug.
3. Install the spark plug to each high-tension cord.
4. Ground the spark plug.
5. Check if spark occurs while engine is being cranked.
NOTE: To prevent excess fuel being injected from the injectors during this test, do not crank the engine for more 5 - 10 seconds at a time.
If the spark does not occur, do the test as shown.
6. Using a 16 mm plug wrench, install the spark plugs.
Torque: 18 N.m (195 kgf.cm, 15 ft.lbf)
7. Reinstall the ignition coil with ignitor.
2. INSPECT IGNITION COIL
a. Remove the air cleaner hose.
b. Disconnect the high-tension cords and ignition coil connectors from the ignition coils.
c. Inspect the primary coil resistance.
Using an ohmmeter, measure the resistance between the positive (+) and negative (-) terminals.
If the resistance is not as specified, replace the ignition coil.
d. Remove the ignition coils.
e. Inspect the secondary coil resistance.
Using an ohmmeter, measure the resistance between the positive (+) and high-tension terminals.
If the resistance is not as specified, replace the ignition coil.
f. Reinstall the ignition coils.
g. Reconnect the ignition coil connectors and the high-tension cords.
h. Reinstall the air cleaner hose.
