The check engine light could come on for a variety of reasons. Your car is loaded with electronic solenoids with voltages running to them. If you are getting low voltage at a Throttle Positioning Sensor for instance you will get a code for that. For around $100.00 at WalMart you can pick up a Code Reader. It will give you a code that you can look up in a service manual and it will tell you what the computer is reading as the problem. It will only get you in the ballpark, not diagnose the problem. For that you can utilize this forum or you can take it to the dealer or a repair shop and they can diagnose it for you, but in any event the Check Engine light doesn't come on for no reason even if the car seems to be running fine.

It could be any of the sensors. Take it to any auto parts store that runs the diagnostic computer on it for free and do that. More than likely it will be one of those sensors. I had a oldsmobile that i had them check and it ended up being the MAF sensor. there are many sensors connected with the service engine light.

Yup. The throttle body connectors have a history of failing on these cars. Replace the throttle body and the wire connectors that go to it, and you're back in business. Not terribly difficult and you can get the parts from any dealer. Saturn actually has a bulletin out on this problem but they won't cover it unless you're under warranty - no recall for this.

take the ground line of the battery and press the brake for a few minutes and if the life is still on have the vehicle scann and clear code and have the emission components for the vehicle check

You can check in the trunk and remove the felt cover see if there is a round panel cover that you can remove to get to the tank. If your unlucky and have to remove the tank you will have to remove the tank. The cover may be under the spare tire so pull it out. It is not to difficult to do, if you drive it till the gas is almost out you can remove the two bolts that hold the tank in place. Use wd-40 to spray on the bolts and also spray the hinges on the oppitse side of the straps. once the nuts are off drop the tank down. You will need to pull the screws off the tank filling tube so it will come down as well. drop the tank down far enough for you to get to the fuel tank sending unit. it will have philips screws holding it in place. Mark two spots with a felt tip pin, (Sharpe) white is better and mark two holes so you can line the it back up for the holes and the hoses. disconnect the fuel line and return line disconnect the battery of the car for safety then pull the wires off it can be a plug or it may have nuts on them. When you remove the nuts or screws out pull the pump out and you will have to angle the pump to get the float out. I recommend that you replace the pump and the sock on the end of the pump. Do not buy after market buy factory replacement only you only want to do this once. mark the new pump holes on the pump using the old pump as an example, will save a lot of time to get it to fit in and match and the lines will line up, tighten all screws up put the lines back on and the clamps and reinstall the tank in place. yo can use your knees to hold it in place till you get the clamps lined up and started. Screw the nuts down till tight and your set to go just hook up the battery again and your set to go.
SIde Note, Never let your car get below 1/4 of tank of fuel, the reason is gas is the coolant for the pump if it goes lower than that the pump will heat up and will burn out. Many people don't know this so I thought I would add this to your knowledge

The information below was complied by me, it explains what causes the check engine light to come on and the process of finding the cause.
When the Check Engine light (or Service Engine Soon or small picture of an engine) is turned on, the systems computer control unit (called the PCM) has sensed a fault in the electronic controls of the engine and/or the emission system. When this happens you will seldom feel the car engine run any different. There are about 200 possible system faults (the gas cap is just one of them) that turn the Check Engine light on, to know what has developed a problem you must have the system tested, this is called an OBD2 fault code test, Kragen/Oriley and Autozone parts stores (USA only) do this testing for free.
I enjoy sharing my 35+ years experience with automotive problems, all I ask is that you please rate my help for Fixya.
