After repairing the cause of the code, you can clear it with a scan tool.
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.

You should have the codes read to see whats wrong.
engine light
If the check engine light is on then have it scanned for codes. I could guess you into bankruptsy. It is cheaper to have it scanned and repaired.
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.
check crank sensor
there are too many codes to figure out why you light is on. the least expensive way to check it out is by going to your local Auto Zone and having them test it for free.
Need to know what code(s) were set and which O2 sensor you changed in order to help you.
Depends on the engine the Park Avenue had in it.
