I'm away from home and on a borrowed computer so no time to search. Can someone give me a link me a list of the codes or tell me what this one is? thanks Larry

 

Is the truck running OK?

This code usually indicates a code was set in the ECM.

 

Ed, it's running fine but we are a long ways from home and wanted to know whether to go ahead and have the family out on the road with it like this. Power is fine, Im pulling about 9K lbs.. Im glad you are on here today, strange how away from home amplifies a problem one is having. Regards, Larry

 

Where are you at? I'm still learning, but agree with Ed about the companion code. Could it be you have had to WOT a few times with your load? Might have set something with that. If possible, pull in to AutoZone or somewhere and have the rest of the codes pulled. It may have just been a glitch that will take care of itself. Good Luck.

I'm in Massachusettes and from what I can read it is a low fuel pressure companion code so should be ok.. I have guages and it never drops below 9 psi so who knows. I wish I knew how to reset the code but Im going to take it home anyways. New fuel filter before leaving home and lift pump sounds ok, shows good fp. Maybe a glitch. thanks all. Im going home
