P0016 Crankshaft and Camshaft correletion.

= The cvvt ( continously variable valve timing) system is installed to the chain sprocket of the intake camshaft. this system controls the intake camshaft to provide the optimal valve timing for every driving condition. The ECM controls the oil control valve (OCV), based from the signal output from mass air flow, throttle position and engine coolant temperature. The CVVT controller regulates the intake camshaft angle
