Check Engine Light 2002 Gs-300

The Light is on. It went off for a while but came back on lately. I checked the gas cap but no luck. What other items make it come on.

if there is an autozone local to you they check it for free. i'd advise you to check it out and get it fixed. some people just reset their ecu by taking off the battery terminals and reconnecting them. but that way you'll never know what was wrong.
