    I have a 2002 Santa Fe, with a 2.7 V6. I just noticed a check engine light
    (it's the wife's car), and when I checked the code, it is a 0449. I checked
    my shop manual, and part of the troubleshooting is to check the CCV. I
    cannot find the definition for the CCV. I also found the fuel cap not quite
    on tight enough. Will this cause the fault code?

    Thank you!

    Maybe, but it's more likely to be the Charcoal Canister Valve.

    CCV stand for " Canister Close Valve ", most likely the fuel cap problem
    cause the code, since it will look to the computer like the CCV was
    fully open. Wait for 4-6 days, if the light turn OFF, that will be the

    It's the canister close valve, also known generically as the vent valve.
    You'll find it with the charcoal canister.

    Although the definition of P0449 indicates a purely electrical condition,
    Hyundai uses this code to mean the same thing as P0446, indicating an
    unexpected vacuum on the evaporative emissions system. This could be
    anything from a faulty fuel tank pressure sensor indicating vacuum to a
    sticking close valve or other restriction preventing proper air intake to
    the system.

    The fuel cap is not a possible cause for P0449 because it's due to an
    unexpected vacuum on the system.

    Well, my code reader, Actron, define it as: 'unexpected LOSS of vacuum'
    ..... I guess I should had check on HMA first.

    Moral, do not believe everything a cheap reader tell you !!!!!
