Be sure the fuses have a clean contact an relays are ok .especially the ASD[ automatic shut down relay ] ,or switch it with the same type relay an retest. it can factor it. But check it all,an ground wires too .
Last resort, the wire where the signal to pcm an from pcm are .Maybe a wiring diagram can be helpful. Be sure pcm has the right power to it too.
Its good you put oem sensors bk in these trucks hate aftermarket sensors!
