How do you shut off the check engine light in a 1998 Subaru Forester?

Your implication that our Foresters have one irritating check engine light echoes what I was thinking on my way to work this morning. Mine wants a new catalytic converter, and so far it only does this when the weather gets cold. My last was an Outback that suckered me into buying converters twice before I gave up on it. But this doesn't answer your question.

Four ways. (1) and best: fix the problem. (2) cheap but temporary: disconnect the battery for 15 minutes. (3) Get a code reader that will read the code and give you the option of erasing it, thus shutting the light off until it sets the code again. (4) take the bulb out or put black tape over the check engine light.

I wouldn't feel good about disabling the check engine light because if something else goes wrong you won't be notified.

Good luck.
