My check engine indicator came on (fuel odor at fuel tank area) replaced fuel cap with nissan part last week prior to getting code P1441 any ideas?

My 2001 altima's check engine light just came on too - code P1441 - either a vacume leak or the bypass valve is malfunctioning. Problem is too complex for the backyard mechanic to diagnose. The fix is easy if you knew exactly what was causing it. afraid you'll have to take it to a tech.
