Please Help 6 codes no guts after changing a A/C compressor 05'Ram 5.9 Cummins-I'm new to the site and very confused-Changed the compressor,I've got a engine light afterwards, truck runs fine except lacking power-I did very light cleaning on engine compartment knew I got the air flow temp sensor wet,got another from Rockauto put it in,still has a engine light- idle alittle high, no guts this time it over heats after about 5 miles-truck cools in about 10 min.Batterys dead next day,batterys checked, both bad got new batterys- still engine light -checked codes and got-p0243,p0480,p0532,p0217,p1755.p2509 please what the hell happened?(for those who need a A/C compressor-Rockauto-$175 new compressor,no core,comes with air dryer and ventura line and seals)

 

I would start by double checking all connections and making sure you didn't get any moisture in any of the plugs.

 

Thanks,I've got it down to 2 codes P0243,P0480

 

You pegged it, plug went bad on the waste gate solenoid ,shares the harness with the A/C compressor,must have just needed a bump and moisture to lose the connection -thanks again

 

Didn't work----removed the 2 prong plug soldered the wires ,still showing waste gate solenoid codes-seems like it would be an awful big coincidence the solenoid goes bad with my batterys and can't find a fuse for it
