There are a few ways to reset the Check Engine Light. You can remove the "NEG" cable from the battery for a minimum of 5 minutes. Or, most local big-chain parts stores, like AutoZone, will clear the light for FREE (except in California) right in their parking lot. Or, you can simply drive the vehicle and the light will reset itself in roughly 50-75 miles of combined city and highway driving.
