On-Vehicle Inspection
ON-VEHICLE INSPECTIONNOTE: In this 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 PERFORM AND PERFORM SPARK TEST
a. Check for DTCs.
NOTE: If any DTC is present, perform troubleshooting in accordance with the procedures for that DTC.
b. Check that spark occurs.
1. Remove the V-bank cover.
2. Remove the intake air surge tank.
3. Remove the ignition coils.
4. Using a 16 mm (0.63 in.) 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 a spark occurs at each spark plug while engine is being cranked.
NOTE:
- Be sure to ground the spark plugs when checking.
- Replace the ignition coil if it receives an impact.
- Do not crank the engine for more than 2 seconds.
If a spark does not occur, perform the shown test:
c. Using a 16 mm (0.63 in.) plug wrench, install the spark plugs.
Torque: 18 N.m (184 kgf.cm, 13 ft.lbf)
d. Install the ignition coils.
Torque: 7.5 N.m (76 kgf.cm, 6.6 in..lbf)
e. Install the intake air surge tank.
f. Install the V-bank cover.
2. CHECK VVT SENSOR OUTPUT VOLTAGE
a. Turn the ignition switch on (IG).
b. Check that the voltage between terminal VC1 and ground is 5 V.
HINT: For the terminal arrangement of the engine ECU, see Control Module Pinout Values of SFI System.
c. While turning the crankshaft pulley by hand, measure the voltage between each terminal.
Check that the voltage changes between the Hi range and Lo range as shown in the table.
HINT: For the terminal arrangement of the engine ECU, see Control Module Pinout Values of SFI System.
