Thanks I'll give it a try

 

Let us know, and we will work from that

 

I just went out and unhooked the battery for about 1 min ... I hooked it back up and started the truck and moved it in the drive way and it stayed off... THANKS
any idea what might of caused it ???

 

Some cars require that you click the cap so many times before starting the engine at a gas station. Or, it will take a few start ups for the light to come back on. It could be something in the EVAP system.

 

I filled it up yesterday and put about 50 miles on it. I had to go to do some work today and it came on after about 1 mile after leaving the house

 

Yeah, normally with vacuum operated systems like the fuel tank it will take a while for the CEL to trigger. Could've simply been the fuel cap wasnt locked, and it came on. In order for the CEL to go off, it wouldve had to go through so many start ups with the cap on or the CEL wouldve had to been cleared. Did you get a chance to read the code?

 

No... I didn't even think about a code, if it comes on again I'll let you know .
It's still under warranty so if it is something to be fixed Dodge can do it The light just bothered me to see the gas cap light on my odometer THANKS FOR ALL THE HELP
