    I am told by the dealer this code will require 1hr of troubleshooting..no
    mention of the added cost of parts. Apparently this is a small leak in
    the evap system. Any experience on this problem out there?

    Loose fuel cap is the most common problem. Could also be a leaking purge
    valve. Have they checked the cap and run an evap self test? This should
    tell them whether the problem is currently present.

    Thanks for the response. I did not get any feedback on the problem other
    than that it will take 1 hr to diagnose..perhaps that is to run the evap
    self test you mentioned. I will make sure I have the cap tight before I
    book it in for any further testing..thanks again.

    I had this happen on my sephia a couple years back..turned out to be a
    bad gas cap. To try and isolate the problem I swapped the cap from one
    of my other vehicles, re-set the ECM and the problem went away. Might
    be worth a try before you take it in.
