Most of the new model vehicle are equipped with variable valve timing inlet (VVTi) camshafts, which help adjust the valve timing of the vehicle when operating on certain loads, to help boost the engine performance at that particular instance. then readjust the timing to the normal point on average working conditions.  But when an ECU commanded the VVTi cam gear to return to the normal point and it's not working, this'll prompt the computer to throw the code P0015 or P0017 or both accuring at the same time, with the check engine showing on the dashboard.
