Threw first codes....

[StephenThomas]

Engine light came on for the first time today. Checked codes and they were: P0341 & P0480. The first is a "Camshaft position sensor performance/rationality" and the 2nd code is: "Cooling fan/Control circuit open (low speed fan relay)".



I've been driving for several weeks/months with the mods listed below and have never thrown a code until today. The only thing I can think of that I did different today was run the AirConditioner.



What do you guys think --- did running my AC cause this? or perhaps it's my TTPM???



Lastly, how do you clear the codes again??



Thx,



Steve

Did I put this in the wrong forum?

Never heard of the AC causing a code to be thrown. If anything I would say it was your box. I know they aren't having issues with them causing codes. But that is the only thing you have out of the ordinary. Then again, there might just be something wrong with the truck.
