I had similar problem in 2003 Maxima. Local mechanic said it was in the evaporative system. Car ran fine. Maxima dealer said some kind of broken valve in evaporaive system. fix was covered under extended warranty. light has never come on again. try the dealer for the fix, most local guys won,t know for sure and will charge you
