ON-VEHICLE INSPECTION

NOTE: "Cold" and "Hot" in these sentences express the temperature of the coils and sensors themselves. "Cold" is from -10°C (14°F) to 50°C (122°F) and "Hot" is from 50°C (122°F) to 100°C (212°F).

INSPECT IGNITION COIL WITH IGNITER AND SPARK TEST





Check that the spark occurs.
1. Remove the ignition coils.
2. Using a 16 mm plug wrench, remove the spark plugs.
3. Install the spark plugs to each ignition coil, and connect the ignition coil connector.
4. Disconnect the injector connector.
5. Ground the spark plug.
6. Check if spark occurs while engine is being cranked.

NOTE: To prevent gasoline from being injected from injectors during this test, crank the engine for no more than 5-10 Seconds at time.





If the spark done not occur, do the test as shown:

7. Using a 16 mm plug wrench, install the spark plugs.

Torque: 17.5 N.m (180 kgf.cm, 13 ft.lbf)

8. Reinstall the ignition coils.
