NP. The codes don't lie (as far as I know, lol )

 

Just kidding I find out that one of the cables from the sensor was smash cut in two but I couldnt tell until I remobe the plastic cover thats the answer I found that circuit it means that a cable is FU****. but thanks. I was just playing with you guys on the first answer but this one is for reals. but tanks you guys really help and the neons.org too.
