Hi,
First, loose gas tank cap can do that. If that's not it, extract trouble
code. Pep Boy does that for you free. I use OBD II scan software with my
laptop. Using this software, I replaced O2 sensor, knock sensor on my
son's 2000 Impreza RS.

Even if the gas cap is the problem, tightening it probably will not turn the
light off immediately. You'll have to drive for some miles before the thing
resets.

If it has been more than two driving cycles with the light on it won't ever
clear on its own.

Go to Auto Zone and ask them to read the check engine fault code. If
you go when they're not really busy, it happens pretty quickly. If
they're busy you'll have to wait.

Once you have the code and description, post again here for possible
issues.

As another poster said though, tighten your gas cap -- the
evaporative pressure sensor in the fuel tank will trip a check engine
light (cel) if the cap is not sealed.

I had that problem, it was a Catalyst problem.
