Ignition Coil: Testing and Inspection

NOTE: "Cold" and "Hot" in these sentences express the temperature of the coils 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 (with igniter).
2. Using a 16 mm (0.63 in.) plug wrench, remove the spark plugs.
3. Install the spark plugs to each ignition coils (with igniter), and connect the ignition coil connectors.
4. Disconnect the 4 injector connectors.
5. Ground the spark plugs.
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 does not occur, do the test as follows:







7. Using a 16 mm (0.63 in.) plug wrench, install the spark plugs.

Torque: 18 N.m (184 kgf.cm, 13 ft.lbf)

8. Install the ignition coils (with igniter).
