The check engine light on a 94 Buick Olds Cutlass is read using an OBDII code reader. It is connected to the port under the dash which interfaced directly with the reader.

Disconnect the battery, wait 10 minutes, and reconnect.
There are pages and pages of things that can cause a check engine light. You need to have it checked with a scantool. Then the code can be diagnosed and repaired.
If the check engine light is on with no codes, you have a wiring or computer issue.
I've had problems with the Intake Manafold and also with the spark plug towers burning out setting off the check engine light. I know there are more but this is just my personal experience with my 1999 cutlass.
The computer stores the codes until it is reset manually. The check engine light does not have to be on to check the codes.
Either try disconnecting the battery for about 10 mins. or have vehicle scanned to determine the problem
It means that you need to get the cars computer scanned to find out what the problem is.
