I have been having almost the same problem with my 2002 Maxima. Dealer replaced Vent Control Valve (on EVAP tank) as well as EVAP canister Purge Volume Control Solenoid under hood due to code 1456. After 2 dealer visits ($700+) code P1491 came up and has been coming back for the last 6 months. Dealer gave me BS, so I then replaced vaccum cut valve, vacuum cut valve bypass valve, and just about EVERY other hose in the EVAP circuit myself. I figure if the dealer is going to just GUESS, that I can do the repairs myself. Still have code 1491. Now I have an EVAP tank on order. If that doesn't fix it I am really stuck, and will likely call Nissan Corporate. I have dropped about $1200 on these EVAP problems so far. Oh, I also replaced the gas cap. No luck.
