On-Vehicle Inspection
ON-VEHICLE INSPECTIONNOTE: In the given section, the terms "cold" and "hot" refer to the temperature of the coils. "Cold"means approximately -10 °C (14 °F) to 50 °C (122 °F). "Hot" means approximately 50 °C (122 °F) to 100 °C (212 °F).
1. INSPECT IGNITION COIL ASSEMBLY (WITH IGNITER) AND PERFORM SPARK TEST
a. Check for DTCs.
NOTE: If a DTC is present, perform a troubleshooting in accordance with the procedure for that DTC.
b. Check if sparks occur.
1. Remove the V-bank cover.
2. Remove the intake air surge tank .
3. Remove the ignition coils.
4. Using a 16 mm plug wrench, remove the spark plugs.
5. Install the spark plugs to each ignition coil and connect the ignition coil connectors.
6. Disconnect the 6 injector connectors.
7. Ground the spark plugs.
8. Check if sparks occur at each spark plug while the engine is being cranked.
NOTE: Do not crank the engine for more than 2 seconds.
HINT: If sparks do not occur, do the following test (See procedure "A"):
9. Using a 16 mm plug wrench, install the spark plugs.
Torque: 25 N.m (255 kgf.cm, 18 ft.lbf)
10. Install the ignition coils.
Torque: 8 N.m (82 kgf.cm, 71 in.lbf)
11. Install the intake air surge tank.
12. Install the V-bank cover.
c. Spark test (Procedure "A")
1. Check if wire harness side connector of ignition coil (with igniter) is secure.
2. Perform spark test with a different ignition coil (with igniter).
1. Replace current ignition coil (with igniter) with a different functioning ignition coil (with igniter).
2. Perform spark test again.
3. Check 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 resistance of VVT sensor.
5. Check resistance of crankshaft position sensor.
6. Check IGT signal from ECM.
