If you are a DIY'er you can get a OBDII scan tool that connects to your laptop that can tell you the error code and allow you to reset your check engine light. This will save you $80 each time over going to a mechanic for a diagnostic. They are easy to use and will help you know what the issues are if you do have to go to a mechanic.

Or you can try disconnecting your vehicles negative battery lead for 5 minutes. That should clear the code. if you check engine light comes back on after several days, you still have a problem

It is very common for many vehicles to drive nicely with the Check Engine light on. This is why so many people simply ignore the light. (BAD MISTAKE)

The true fact is that the computer is trying to tell you that there is a malfunction in one of the many different systems and/or electrical circuits that are monitored by your onboard computer network. Some of the possible malfunctions are simple and do not require much in the way of diagnosis or repair. Other possible problems are not so easy.

At the very least, you are wasting expensive fuel. The engine computer cannot properly maintain the correct air/fuel ratio when there is a system malfunction and the light is on. At worst, you could be causing severe damage to some very high-priced parts of your car(including the engine and/or transmission and catalytic converters) if you continue to operate it with the light on. Chances are very high that the longer you drive it with the light on, the more expensive it will be to fix it when you do finally fix it.

The only way to find out the nature of the failure is to scan your onboard computer network and retrieve the Diagnostic Test Codes (DTCs) (AKA - Fault Codes) that have been recorded as a result of the malfunction. These codes are then used to identify the correct diagnostic and repair procedures.
