Code P1111 2003 Nissan Sentra Description

The intake valve timing control solenoid valve is activated by ON/OFF pulse duty (ratio) signals from the Engine Control Module (ECM). 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.
The Diagnostic Trouble Code (DTC) when an improper voltage is sent to the ECM through the intake valve timing control solenoid valve.
