After reading a old post by user Costee he mentioned that the VTC had its own 2 sensors & the cam/crank had their own 2 seperate senors. Are these sensors really different per se. Do I need to swap out the 2 VTC sensors for the correct part? It appears to be very similar only difference is just the angle. Wil this function correctly? The car is running ok no codes to report... any feedback would be great, thanks
