On-Vehicle 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). (See REMOVAL )
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 in Fig 1:

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). (See INSTALLATION )

Clean the spark plugs.
If the electrode has traces of wet carbon, allow it to dry and then clean with a spark plug cleaner.

Air pressure: Below 588 kPa (6 kgf/cm² , 85 psi)

Duration: 20 seconds or less

HINT:

If there are traces of oil, remove it with gasoline before using the spark plug cleaner.
