Description
Intake valve timing control solenoid valve is activated by ON/OFF pulse duty (ratio) signals from the ECM.
The intake valve timing control solenoid valve changes the oil amount and direction of flow via the intake valve timing control unit or stops oil flow.
The longer pulse width advances valve angle.
The shorter pulse width retards valve angle.
When ON and OFF pulse widths become equal, the solenoid valve stops oil pressure flow to fix the intake valve angle at the control position.

DTC CONFIRMATION PROCEDURE
1.PRECONDITIONING
If DTC Confirmation Procedure has been previously conducted, always perform the following before conducting the next test.
2.PERFORM DTC CONFIRMATION PROCEDURE
Diagnosis Procedure
Regarding Wiring Diagram information
1.CHECK INTAKE VALVE TIMING CONTROL SOLENOID VALVE POWER SUPPLY CIRCUIT\
2.CHECK INTAKE VALVE TIMING CONTROL SOLENOID VALVE OUTPUT SIGNAL CIRCUIT FOR OPEN AND SHORT
3.CHECK INTAKE VALVE TIMING CONTROL SOLENOID VALVE
4.CHECK INTERMITTENT INCIDENT
Component Inspection
1.CHECK INTAKE VALVE TIMING CONTROL SOLENOID VALVE-I
2.CHECK INTAKE VALVE TIMING CONTROL SOLENOID VALVE-II
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.
