You will need an OBD2 scan tool or code checker to read the code. There is no shortcut on resetting the lamp. It's coming on for a reason. Find out which code is setting, repair the condition and then clear the code. Most of the time, once the repair is made, the vehicle will need to make two or three "trips" without a failure before the lamp will reset. Russtech67
The check engine light on a Buick Regal can be reset with a special diagnostic scanner. This can be performed at a car dealership or service garage.
I have a Buick Regal LS and I had them run a computer diagnosis and it was due to the gas cap not fitting properly. There is an electronic sensor there. Most automotive stores will do this check for you free of charge.

The check engine light on the 1998 Buick Park Avenue can be reset by disconnecting the battery for a few minutes and then reconnecting it. The check engine light is only going to stay off if the problem that created the light is fixed.
