The gas cap light is not just a warning for the fuel cap, but also an alert that there is a problem in the emissions system as well. There are literally dozens of sensors/parts in the emissinos system, so you will need to have the "p-codes" read from the on-board computer. Once you have these p-codes you can more accurately and efficiently diagnose and repair the faulty sensor/part. Most local Auto Zone locations will read these codes for you for Free.
