This truck is my brothers he's getting a codes P0641 p06a6 p069e
It all comes back to 5 volt reference, A circuit range and fuel pump module truck runs good does everything it's supposed to just has a engine light on and it's due for emissions I am lost check the volts at the sensors I'm getting 5 volts at mass air I believe it's the map sensor on top of intake manifold any help or if you guys seen problems with these trucks where to start first broken wire somewhere maybe the PCM is bad I do have a fuel pump module but it needs to be programmed if I go that route
Thanks

Well put the snap on scanner on the truck this morning when I got to work the only code I have is P069E so looks like fuel pump control module needs to be replaced
