agreed, it could also be that the light is broken as well.

Can't really disagree with any of the above...but for emphasis...the check engine line indicates that a "trouble code" has been generated by the on board computer, indicating some problem with the systems monitored by it. These codes can be read by a "code reader", ranging from a relatively simple reader at Advance Auto, or Auto Zone, which they will do for free, up a level to code reader's used by garages which are more complex and cost a little...here around $25-$50, up to the dealer who can charge $50-$100; each level, more sophisticated. Start at Auto Zone or Advance, only move up if necessary. My codes have always been a loose gas cap, or a bad oxygen sensor.
Good luck...

(Check Engine Light)
There are many components that work together in the engine to maintain optimal engine performance and economy.
A service engine soon, or check engine light indicates that there is a sensor that is reading a condition that is "out of range".
Simply resetting the light does not solve the initial cause of the problem.
Replacing a number of parts trying to troubleshoot the problem in the hopes of getting the light to stay off is a tremendous waste of time and money.
The simplest, and most economical way to alleviate your issue, is to have an engine diagnostic done by a reputable shop to determine what caused the computer to signal you to begin with. Just reading the computer codes may not find the "cause".

Most cars have computerized engine controls. They rely con sensors and actuators to do the job. Sensors input information to the computer, which calculates and sends signals to the actuators that control the operation of the engine. Any of these sensors or actuators could be not working properly or sending wrong signals to the computer. As a result, the light goes on. Go to the shop, where they have another computer that communicates with the computer in your car and analyzes the error code. The mechanics will then replace the defective part and that's it!!!

There can be literally hundereds of things that are wrong. The CEL comes on when the ECM detects that a input or output is giving back false information. A dealer can check and tell you what is wrong. Some basic things you can do is check your gas cap. I know that sounds stupid but if your gas cap was not tightened back up all the way it will cause you CEL to come on.

The first answerer is correct, it could be anything in the world. However, you don't have to go to a shop that will charge a minimum of $75 to hook it up to the diagnostic machine. You can go to AutoZone or Advanced Auto Parts and they will tell you for free. It could be something as simple as you did not tighten the gas cap enough last time you filled up.

did you just get an oil change? if you take it to a place other than a dealership, odds are they did not reset the internal timer for your oil change. look in your manual. it should have a part that explains how to reset this. usually you have to turn the car on, off, then hold in the odometer for a few seconds.
