    Fuel tank, Check engine light

    I have a 98 Altima automatic
    about 60K
    Around June 03 , I had a check engine light come on,mechanic said he
    replaced the fuel pressure valve.
    and cleared the alert.
    I had no problems filling the tank at that time.
    exact info listed on work report is

    found faulty vent control valve

    replace valve – reset readiness


    Today I tried to fill the tank, and fuel came back out.

    I had half a tank still , so I drove around a bit, no check engine
    light came on.

    The car has been sitting idle for about 3 weeks in sun , so I though
    perhaps an issue with pressure/heat

    After about 20 minuets, and after i tighten the cap some more, the
    check engine light came on.

    Now the fuel cap is old, and looks like it could be replaced.

    If I replaced the fuel cap, cleared the check engine light could this
    solve my problem ?

    Hey Russell, I'm not sure if a new cap will help you, but here's something
    you might want to check on. I found out today that my sentra has a fuel
    filter inside the gas tank. You might want to call the parts dept. at
    Nissan to see if yours is located in the gas tank. They told me that the
    fuel filters in the tank are supposed to last past 100,000 miles though,
    so this is just something you might want to check into. There might be
    some sensor that is bad too. I'm finding out Nissan is pretty bad with
    these dang sensors going bad. If you can drive it to a local AutoZone,
    they can hook it up to a code reader for free and hopefully point you into
    the right direction. Good luck.

    Have a close look a the gas cap, maybe the seal is worn or broken.
    Try to give the gas cap a few extra turns when you put it back on.
    A loose gas cap can cause the check engine light to come on for the Nissan
    Quest.
    One of the test during the Smog inspection test is to remove the gas cap
    and run a pressure test.

    Yup, it has something to do with pressure. Its all the newer cars I
    believe, my mom had this problem with her Civic. Turns out the cap wasn't
    sealiinga nd that was causing the SES light to come on.
