I had to jump start my car 4 years ago and the 'check engine' light has been on. on 2007 Chevrolet Cobalt

the light has been on for the last 40,000 miles and I have had no problems with the car whatsoever. oil changes and tires have been regularly serviced, and no other problems have occurred. Could this 'check engine' light be just a short or something? Nothing appears to be wrong with this car for the last 4 years or 40,000+ miles.
