Code P0022 Infiniti Description

This mechanism hydraulically controls cam phases continuously with the fixed operating angle of the intake valve. The Engine Control Module (ECM) receives signals such as crankshaft position, camshaft position, engine speed, and engine coolant temperature. Then, the ECM sends ON/OFF pulse duty signals to the intake valve timing control solenoid valve depending on driving status. This makes it possible to control the shut/open timing of the intake valve to increase engine torque in low/mid speed range and output in the high-speed range.
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.
