The simple answer: Disconnect the negative battery lead for 1/2 hour. The codes will reset to factory defaults and the check "engine light" will be out. After several driving cycles the CPU (brain) will pick up new codes. If the light comes back on then, you've got a problem. The downside: You will also lose the radio security code, so you'll have to punch that in-- find it first, or be without tunes.
