    hello everyone, I am new in this forum, I have chrysler Town & country 2002 LXI .a week ago when I pump gas , the gas nozzle did not shut off when the tank is full, cause spillage, after that the engine light went on, I plug it in the scanner and get the code P0455 large leak detected. I craw under the van and check all the hoses but I did not see any crack. a friend told me that it could be the gas cap, I got the new gas cap at dealer and put on , erase the code, after 2 days the check engine light went on again with 2 code P0442 and P0455, I dont know exactly where to find the leak? people told me that they have to use smoke machine to find the leak. Is there any other way to find the leak and pinch point the problem?Because I dont have the smoke machine... Beside the hoses and gas cap, what part of the EVAP system should I blame? purge solenoid?, charcoal canister, or leak detection pump? please help........

    Anything that is damaged, cracked, leaking or loose in the evap system will cause those codes.
    All repairs should start with a good visual inspection any anything obviously wrong/damaged should be addressed first.

    When I looked under the van, I noticed the white OEM plastic hose clamps were busted off of two of the EVAP hoses. Could that be the reason for my P0442, 455, and 456?

    It could be. I replaced all my vacuum lines & those clamps when I had that error.

    It has not come back at all.

I knew about the codes but I haven't had the time to look for any cracked hoses. I got under the van yesterday (after the same codes came on again) and started looking around. I noticed that the vapor canister looked like it had been wrapped a couple time with electrical tape. This wasn't there before. It looks like on the front side of the vapor canister that there is some type of port that they covered with electrical tape. I don't have a fsm for my van 2001 T&C Ltd 3.8. Does anyone have a drawing of the vapor canister so I can see what it is that they covered with tape. I took some pictures of the vapor canister. The picture with the wrapped up port in mention is seen through a mirror so to try to make it more visable. Can anyone make any light of this?

    It makes me wonder how a Dealer can stay in business making these types of repairs!!!
    I am having the same problem on my 2001 3.3L. I also was told that the gas cap was the problem, but it did not fix the problem. Every time I reset the code it comes right back. I need to check those areas on my van also.

    I agree that the best way to solve the (p0442 p0455) issues is a REALLY good visual inspection of all of the hoses on the emission system. Spend some time on the board and search p0442 and p0455 and you will find all the info you need. Good Luck

    Dear Tomy, since you mention that this occured right after you overfilled, I would suspect that is the problem. If gas overfills and runs into the vacuum/purge hoses going to the vacuum canister, it can create a liquid blockage that keeps gases from properly circulating, also the gas may damage parts of the system. This has been mentioned quite a bit on Car Talk from people continuing to fill the tank past the click off and they warn against it. It may go away if gas has just filled the line after that gas evaporates. But watch the click off and stop! Otherwise you may need to replace some of the components listed above.
