i hav been getting this code since its been cold in arizona but i hear everyone talking about replacing batteries and cables but this didnt work on my truck!! while driving within the first few min, my truck shuts down like it loss all power to the truck but in the mean while it kick the check engine light on and then it seems to drive just fine after the check engine light come on. but after awhile the truck will clear the code it self when its a warm day out but if it gets cold it does it again. and the dealership cant figure it out here in phoenix!

 

You can see the links in my signature and download the Service Manuals for help with diagnostics and those codes

Also, need to know what yr/mk/mo/eng

 

its a 2006 dodge cummins 5.9, 2500 4x4

 

See if this helps
