Yeah... I'd advise having AutoZone run a scan, to see what the error code is. 
Why on earth would they make the engine light come on when you're due for an oil change? That would definitely be annoying. I've got a dedicated light that will turn on when the car wants an oil change... I prefer that by far. I don't know about anyone else, but if my engine light comes on, I immediately either stop driving, or drive straight to the nearest AutoZone, depending on the circumstances. I'm amazed at how many people don't care what error code is being thrown.

To the OP.
Could be one of the exhaust sensors picked up something funny, but not enough for you to feel it in the engine or have it stop.
I'm not sure about your car since it's a 2002, but most older cars you can sometimes check what the error code is with an LED. You can also re-set the code by simply using a paperclip. Try digging around the net with Google for more info.
You can also go to a major library in your area if there is one and look at some of the repair manuals for your car. You may need to call around to see which library has them. The bigger the better. The manual should give info on how to check the error code and what it means.

I looked at the Manual and it pretty much restated what some of you said.
A) check fuel cap and that you have at least 3 gallons of gas.. if it was the fuel cap it could take a couple of times driving for the light to go away.
B) if light does not go away it could be a emission control malfunction.. have the car checked by the dealer.
That's about it on that.
I already went ahead and took off the fuel cap and put it back on tight and will see if it goes away, but i plan to stop by autozone tonight or tomorrow morning.

I say if you're gonna modify your car, just unhook the PCM and put a carburetor in it.
Sorry, I like domestics too much, don't I...
Keeping your fuel cap loose causes other problems, too. If your fuel filter isn't up to par, dust in your engine can grind the parts and cause premature failure. You wouldn't want atmospheric water vapor in there, because it'll condense every morning and put water in your tank.
Update:
I went to Autozone this morning and had them check the message.
It came up with P1456 Manucfature Control Auxiliary Emission Controls, guy told me to talk to my dealer.
He also reset the light.
Edit: Anyone have experience on what that error message could actually mean.. the guy at Autozone was not sure.

not sure what bootymac is saying, but it could be from your gas cap not being on tightly. If it doesn't come back, don't worry about it. and tighten your gas cap.
P1456 - Fuel Tank Temperature Sensor Circuit Malfunction
This is want my generic code book says. I don't have a Nissan specific manual here at work. If the light comes on again I would take it to the dealer or a trusted repair shop for diagnosis.
Good Luck,

So even though the guy at Autozone turn it off, if it is a real problem it should come back On?
How much time should i consider it enough to say, i guess it was just a random error.
Update 10/28/2005
I had taken it to Autozone for the code and got the following
P1456 Manufacture Control Auxiliary Emission Controls.
Finally took it to Nissan because they had this 100 point free inspection. I told them about the light, was told it would cost $85 to do a full diagnostic of the engine.
they came back with the same code error P1456, and came back with ?fuel filter cap seal dirty, Intake system needs cleaning?
They recommended I get the Fuel Injection service to help with the problem which was $159 and I also agreed to have Battery Service $39.
In all I paid $309.
But the stupid light came back on!!
Do you think, I have the right to complain and have it checked out for free?

I can't find any Nissan specific info on that. The Honda DTC says there is a leak in the EVAP system, which would seem to match with the autozone dtc. I think the dealer was in the wrong area. They saw intake system and sold you the fuel injection service. The evap system takes gas vapors from the gas tank and eventually runs it into the intake manifold. I think that's where they should be looking. I'd lean more to a leak in the rubber hoses to the charcoal canisters. But i'm just a shade tree mechanic so don't take my word for it.
I don't like the word 'recommended' In my Lexus factory manual, they list all the DTCs and give you a flow chart to diagnose the problem. I'd go in and ask to see that part of the manual to see if it says anything about the fuel injection service. If it doesn't, demand your money back and make them use the flow chart to diagnose it.
Of course just because the light came back on, doesn't mean it's the same DTC

Yes, the dealer sold you a service to resolve a check engine light and it didn't fix the problem. I would go back and explain to them their service repair didn't fix your concern and you want it repaired correctly. If they say they have to charge you for diagnosis again explain you have already paid for the diagnosis for the P1456 code and won't pay again because their repair didn't fix the problem.
Alright, thanks. I will call them up..
I just called them up. I can bring it for another diagnostic, if the code is different they will charge me again, otherwise, it will be free... but obviously whatever the problem is i have to pay again to try and fix it.
