This might sound stupid, but I had the light come on in my 98 s-10 and it was because my gas cap was not on right. I went to the dealer and told them that the check engine light came on and he went stright to the gas cap and fixed it. I felt like a girl
it's really not so stupid, i am a service advisor at a chevy dealership, i see this almost everyday. gas cap loose,not tight enough, or on crooked, anything that would make it not seal will make the ses light come on. part of the obd2 diagnostics, way too sensative if you ask me. I do not believe there is a way to retrieve codes from an obd2 system using a jumper wire on the aldl like you used to could do. If it's not you're cap then i would advise going to a dealer. i have seen way too many people waste their money(sometimes hundreds) trying to fix it in the driveway, only to end up at the dealership to get it fixed

Yep, "No user serviceable parts inside" as they say. One thing to try sometimes helps is to unhook the ground cable on the battery for a minute and see if it will clear the code. Could have been an intermittent fault. A spark plug misfire can set the light. Pretty touchy computers these days.
