If the SES light has been on for months non-stop...

...is it pretty much safe to say that it's the oxygen sensors that are causing it? I haven't changed anything about my car either and its daily driven. The light has been on for months.

Oh and I can't seem to be able to scan it since I have a problem as described here .

Thanks for any input.

No, is not safe to make such an assumption. There are literally hundreds of things that can turn on the light.

Why not get it scanned free at AutoZone and stop guessing?

OK... sorry, saw your other post. Get a dealer to check it. SES might be for faulty PCM
