my buddy has a 07.5 while on his way back from harrisburg it started bucking and lots all of its power and i had to tow him home. these are the codes that came up. mods done to truck all deletes and smarty 14me. i think there is a wire burn out somewhere that is causing all of the low voltages.

1.exhaust pressure sensor 1 low
2. fuel pressure sensor low
3. manifold absolute pressure senor circuit low
4. crankcase pressure sensor circuit low
5. senor reference voltage 2 low
6. fuel system over pressure relief valve activated
7. fuel rail pressure too low
8. camshaft position senor performance bank 1 senor1

anyone have and ideas

 

possible bad ground some where something to look at

 

If your hunting A wiring issue then have A look at the serpentine belt. And any of the wires running round close to it. the wires too and around the AC Compressor were A common sticking point in the earlier units. Haven't had to crawl mine yet to see if this has potential or not. But may give you something to look for. Good thing to do is check fuses and what else is connected to them for the control of the things blowing codes. See if there is A common underlying connection.

My truck has the wires around the AC Compressor all messed up. Will the dealer fix this or do i have to?

 

Should be warranty work. Depends on the cause.
