Nissan Altima: Altime Engine problem

I own an 2004 Altima 2.5SL, I had a problem with the engine and the service
engine soon appeared on my dashboard. The engine have been serviced but the
light still appears. What should be done.

goto and Autozone and they'll pull the code for free.. probably just a loose
gas cap.
an oil change doesn't remove the light. the light turns on when a sensor
isn't working right.
