Intake Valve Timing Control Feedback Control
WARNING: This page is about a different car, the 2013 Nissan NV200. However, it is still accessible from the selected car via links, so may be relevant.
Cam Position Detection
The camshaft position sensor mounted at the rear of the cylinder head detects a cam position, by using the groove on the plate located at the rear of the intake camshaft.
Feedback Control
The camshaft position sensor feeds back an actual cam position signal to ECM. Based on the signal, ECM controls the intake valve timing control solenoid valve to satisfy the optimum target valve opening/closing timing according to a driving condition.
