What might be the reason for the check engine light in my 2002 Chevy Cavalier turning on?

Here is a revised version of the text:

The check engine light on the 2002 Chevy Cavalier cannot be reset. It illuminates when there is a problem with the car, but the issue could be caused by various reasons. Therefore, it's not recommended to spend time searching for a random issue unless it's a clear problem. The best course of action is to take the car to a mechanic and have them use an OBD tool to scan it. This will help identify the trouble code and pinpoint the problem area. Knowing the issue will enable you to get it fixed, which will then turn off the light. One simple thing to check first is the gas cap and fuel door. If the cap is missing or the door is open, it can trigger the light. This is a minor issue that you can resolve without visiting a mechanic, so be sure to inspect it yourself initially.
