Do you mean the yellow light with the little engine picture on it?

If so, go and get the code read (free at AutoZone/PartSource).

The light can illuminate for any of a hundred different reasons, so you
absolutely need the error code behind the illumination.

DO NOT disconnect the battery! The light WILL go off if you do that, but
you will also lose a very valuable piece of diagnostic information!

Once the code is read, THEN you turn the light off and see if the same code
comes back.
