CODE P0455

2000 Dodge Neon

I found out that the code P 0455 means evaporative Emission Control System Leak Detected.
Could someone please explain to me what this means and how do I fix it? Thank you so much.

That code means large leak. A missing or loose gas cap may cause it, a component failure, fuel tank neck, evap hose disconnected are some possiblities. Check the fuel cap and make sure it has no cracks in the gasket and is tightend down good. Otherwise a smoke machine will need to be used to find it.
