Code P0011 2004 Infiniti I35 Description
The intake valve timing control solenoid valve changes the oil amount and direction of flow through the intake valve timing control unit or stops oil flow. The longer pulse width advances the valve angle. The shorter pulse width retards the 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.
