You can disconnect the positive battery terminal for 15 minutes and then reconnect. If there aren't any hard codes, the CEL will stay off. OR, you can use an OBD-II diagnostic tool and erase any codes that way.

Also depending on the vehicle after a designated number of ignition/start cycles with no codes present, the light will go out by itself.

Be careful about battery disconnect you could activate anti theft, your best bet is to remove all of the ECM main power fuses and KAM fuse and wait a few minutes then reconnect, that should reset the ECM to factory specs.

Good catch Mr. Shoes. I've never had that happen and watch, the next time I disconnect my battery it'll happen. Haha :P
