WARNING: This page is about a different car, the 2016 Nissan Murano. However, it is still accessible from the selected car via links, so may be relevant.

The intake valve timing intermediate lock control improves the cleaning ability of exhaust gas at cold starting by fixing the camshaft sprocket (INT) with two lock pins and bringing the cam phase into intermediate phase.

Cam phase is fixed at the intermediate phase by two lock pins in the camshaft sprocket (INT). ECM controls the intermediate phase lock by opening/closing the intake valve timing intermediate lock control solenoid valve to control oil pressure acting on the lock pin and locking/unlocking the lock pin.
