Exhaust Valve Timing Control Feedback Control
WARNING: This page is about a different car, the 2019 Infiniti QX60. However, it is still accessible from the selected car via links, so may be relevant.
Cam Position Detection
The exhaust camshaft position sensor detects a cam position, by using the groove on the plate located at the rear of the exhaust camshaft.
Feedback Control
The exhaust camshaft position sensor feeds back an actual cam position signal to ECM. Based on the signal, ECM controls the exhaust valve timing control solenoid valve to satisfy the optimum target valve opening/closing timing according to a driving condition.
