Chrysler LHS Code P0455

Yesterday, the check engine light came on on my 2000 LHS. Last month I
replaced the gas cap when this happened and everything was OK.
I checked the gas cap and it was completely closed. I disconnected the
battery and the code disappeared until after I drove it to work and it
came on this evening on the way home.
I have the same code, P0455, EVAP system leak detected. Are there any
other obvious places to check for leaks? Somebody recommended that I
check the gas filler seal to the gas tank.
Any other suggestions?

Thanks in advance,

I recently spent a few hundred bucks for a smoke test on my 2001 minivan to
find a tiny leak in a rubber hose going to the fuel tank. They also replaced
the clock spring to fix the airbag light, but that started occasionally
coming back on again. It is such a pia to take the car to the dealer, as he
has no loaners, that I put up with it.

The purge valve is what normally causes this code to set on that model. I
would recommend the smoke test before you start tossing parts at it.

you need to inspect all the hose's for the system to the tank if you smell
a faint hint of gas then there is a leak somewhere alot of techs do not
understand this system so you need to find a good one or the just throw
parts at it and wasting your money
