Exhaust Valve Timing Control Position Sensor
WARNING: This page is about a different car, the 2019 Nissan Armada and 2018 Nissan Armada. However, it is still accessible from the selected car via links, so may be relevant.
Exhaust valve timing control position sensor detects the protrusion of the signal plate installed to the exhaust camshaft front end.
This sensor signal is used for sensing a position of the exhaust camshaft.
This sensor uses a Hall IC.
Based on the position of the exhaust camshaft, ECM controls exhaust valve timing control solenoid valve to optimize the shut/open timing of exhaust valve for the driving condition.
