My 98 Pathfinder had this code when I bought it. It was a clogged EVAP purge valve. It was completely full of carbon from the canister!
I successfully cleaned mine out instead of replacing it. My CEL turned off almost immediately!
If you dismantle yours, make sure you don't break the metal tabs that hold it together. Also, try to shake out the rest of the carbon in the hose leading to the valve. Before you put it all back together, install a cheap and clear fuel filter in front of the valve. Now you can see it all building up instead of clogging your valve. Of course, you'll need to remedy the charcoal canister problem at some point.
