Most vehicles have a reset button accessible from the accessory fuse panel which is usually behind the dash panel where the shotgun passenger door opens up. Turn the key to the on position and press and hold the reset button for about 10 seconds. The lights should flash and the codes will be reset. The light may come on again if the problem still persists.

I reset the check engine light on my jeep by disconnecting it from the battery.
I was told by a co-woker that if you disconnect the negative battery cable for about 20 minutes or so that will reset the service engine light.
