Component InspectionINFOID:0000000005532477
INTAKE VALVE TIMING CONTROL SOLENOID VALVE
1. Disconnect intake valve timing control solenoid valve harness connector.
2. Check resistance between intake valve timing control solenoid
valve as follows.
If NG, replace intake valve timing control solenoid valve.
If OK, go to next step.
3. Remove intake valve timing control solenoid valve.
4. Provide 12 V DC between intake valve timing control solenoid valve terminals and then interrupt it. Make sure that the plunger
moves as shown in the figure.
CAUTION:
Do not 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.
If NG, replace intake valve timing control solenoid valve.
NOTE:
Always replace O-ring when intake valve timing control
solenoid valve is removed. Continuity should exist.
