Component Inspection
INFOID:0000000009719891
1.
CHECK INTAKE VALVE TIMING CONTROL SOLENOID VALVE-I
1.
Disconnect intake valve timing control solenoid valve harness connector.
2.
Check resistance between intake valve timing control solenoid valve terminals as per the following.
Is the inspection result normal?
YES
>> GO TO 2.
NO
>> Replace malfunctioning intake valve timing control solenoid valve. Refer to
2.
CHECK INTAKE VALVE TIMING CONTROL SOLENOID VALVE-II
1.
Remove intake valve timing control solenoid valve. Refer to
2.
Provide 12 V DC between intake valve timing control solenoid
valve terminals 1 and 2, and then interrupt it. Check that the
plunger moves as shown in the figure.
CAUTION:
Never apply 12 V DC continuously for 5 seconds or more.
Doing so may result in damage to the coil in intake valve
timing control solenoid valve.
NOTE:
Always replace O-ring when intake valve timing control
solenoid valve is removed.
Is the inspection result normal?
