[QUOTE="Tiha, post: 1564080, member: 33189"] New sensor in. Interesting note. My 2016 reads 320 psi KOEO. New bosch sensor reads 332 psi, KOEO as well. No change in reading while cranking, still dead. Got me to thinking, so I put the old sensor back in. Plugged the return line to the tank. My psI went from 42 to 96 and stayed. It did this way back when I was testing before swapping fuel system. That proved the sensor and PCM are reading pressure changes. So I said screw it, I cranked it with the return line blocked off. Thought well if the cp4 is building pressure it will probably blow a return line or something. Nope, nothing. I need to call supplier again. It has to be the pump. Was thinking about throwing another PCV in it, but this is ridiculous. Can play this what if game all day. Video with oil switch PID and new pressure sensor [MEDIA=imgur]a/TMYh6qB[/MEDIA] [/QUOTE]
