On-Vehicle Inspection

ON-VEHICLE INSPECTION

NOTE: In this section, the terms "cold" and "hot" refer to the temperature of the coils. "Cold" means approximately - 10 to 50 Degree.C (14 to 122 Degree F). "Hot" means approximately 50 to 100 degree C (122 to 212 degree F).

1. PERFORM SPARK TEST
a. Check for DTCs.

NOTE: If a DTC is present, perform troubleshooting procedures for that DTC.

b. Check if sparks occur.
1. Remove the intake air surge tank.
2. Remove the ignition coils (with igniter).
3. Using a 16 mm plug wrench, remove the spark plugs.
4. Install the spark plugs to each ignition coil (with igniter) and connect the ignition connectors.
5. Disconnect the 6 injector connectors.
6. Ground the spark plugs.
7. Check if spark occurs at each spark plug while engine is being cranked.

NOTE:
-Be sure to ground the spark plug when checking.
-If the ignition coil has been struck or dropped, replace it.
-Do not crank the engine for more than 2 seconds.

c. Perform the spark test according to the given flowchart.
1. Check that the wire harness side connector of ignition coil with igniter is securely connected.




2. Perform a spark test on each ignition coil with igniter.
1. Replace the ignition coil with igniter with a normal one.
2. Perform spark test again.




3. Check the power supply to ignition coil with igniter.
1. Turn the ignition switch on.
2. Check that there is battery voltage at ignition coil positive (+) terminal.




4. Check the resistance of the VVT sensor.







5. Check the resistance of the crankshaft position sensor.







6. Check the IGT signal from the ECM.




d. Using a 16 mm plug wrench, install the spark plug.

Torque: 25 N.m (250 kgf.cm, 18 ft.lbf)

e. Install the ignition coils (with igniter).

Torque: 8.0 N.m (82 kgf.cm, 71 in.lbf)

f. Install the intake air surge tank.
