Oil level may be a tad low. When the engine is running the light is made to go out. Same thing on my '97 Grand Prix 3100.

See if you can get it to an auto parts store and have them check for codes. If there are none then at least it is not likely a serious issue.

there is one level switch in the bottom of the oil pan and another pressure switch on the front side of engine block check them for leaks/bad contacts/loosen plugs/wiring you can swap the sensors with known working if you can access them from under the car here it was difficult to got the level sensor (chines aren't aware yet) but for pressure switch it is very cheap.
