When cranking PCM look for signals from the sensors to identify where is each cylinder and to fire
so if a signal is missing or interrupted check engine light will come on to let the driver know that there is a problem
in your case the cam sensor is the trouble area
I would start by checking it and its plug and wire
(replace cam sensor )
