Code P1111 2005 Nissan Maxima Description
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.
