P0081
P0075, P0081 IVT CONTROL SOLENOID VALVE
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 through intake valve timing control unit or stops oil
flow.
The longer pulse width advances valve timing.
The shorter pulse width retards valve timing.
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.
