98 Altima!Need help

Hi! I am driving a 98 Nissan Altima with just 53000 miles. For a week or so my "Service Engine Soon" light stays on. I scanned the car for problems and it gave me a code (Something p14...which i dont remember) but i do remember it said near the code like this "Auxillary Emissions Controls". I have no idead what that means. I will really appreciate if anyone in this forum can help me with the problem. How can i check it and how will the "Engine service soon" light disappear.
Thanks.

Failure of the Canister Vent Control Valve can cause the check engine light to illuminate. The cost to repair the Canister Vent Control Valve is estimated at $59.93 for parts and $52.00 for labor.
