the gas cap. It still does it. I can smell gas when I open the door to put gas in, have seen a little gas around the edge. Took that cap back, replaced it and the sensor came back on again. Interestingly, I am turning the cap at least three times to hear the clicks, but when I go to take it off, the cap is not on tight. I'm getting the caps at Advance Auto, do I need to get one from Dodge? Or what else do I need to have investigated?

Thanks for your advice!

 

Are you sure they are selling the right cap to you.

 

are looking it up on the screen after putting in the car info. I took one back, got another one and still the same thing.

 

I have never had trouble with my gas cap and even though its tightened to where it clicks it seems loose and yet there are no fumes.

 

I highly doubt that you've got a gas cap problem. These vans are known for leaks in their evaporative emissions hoses. Click on this link for an article on how the Chrysler EVAP system works:
