Too bad you can't get the code off your digital odometer. I'd take it to Autozone and get a free scan. They'll get the code for you, tell you what it is and reset it if you want (to see if the code gets thrown again or if it was just a phantom code) Sometimes a small misfire or a one time problem will cause the light to come on, the computer retains the code but the problem may not still be present. Just get the code read, find out what it is and go from there. A steady light isn't a huge deal, it could even be a loose or unseated gas cap. As long as the light isn't blinking, you're in good shape. Get it read, find out what it is and reset the computer to see if the code comes back up. Good luck.
