    This diagnosis detects a very large leak (fuel filler cap fell off etc.) in EVAP system between the fuel tank and EVAP canister purge volume control solenoid valve.
    Use only a genuine NISSAN fuel filler cap as a replacement. If an incorrect fuel filler cap is used, the MIL may come on.
    If the fuel filler cap is not tightened properly, the MIL may come on.
    Use only a genuine NISSAN rubber tube as a replacement.
    This gives you a ball park idea. You might want to get a new gas cap from the dealer first. You might get lucky.
