Question about 1999 Saturn SC
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.

A rabbit crawled up under my daughters Saturn SC1 hood and chewed off wires going into the engine or tranny housing and the brake fluid resevoir. Had all kinds of warning lights. Some of the wires going into the engine block were chewed off really close to the housing but there was just enough wire sticking out to reconnect them by soldering them together and covering them with heat-shrink tubes. All is well now.
Try to find the other end of that yellow wire and repair it. Good luck.
