Pull the codes from the computer with a scanner, match the code to the troubleshooting procedure, follow the procedure to find the source. Repair the source, light will go out if that was the only problem. There are "monitors" or self test the computer runs the car through, if a problem occurs, it may not run all of the self tests until that problem is taken care. Therefore, another problem may exist.

Depending on where you live, you can pull into any AutoZone store. They will read the codes from any OBDC2-compatible car, FOR FREE.
