O2 sensor light

[bilzner]

My O2 sensor light is on constantly, it just started 2 days ago and hasn't gone off! Anyone know how to shut it off? I mean I read somewhere that this isn't too much of a problem and that just the sensor light comes on for no reason.. what do you guys think? Someone know how to turn it off or reset it?

It is supposed to come on at around 90k miles. Mine never did though... all I know is there is a switch somewhere under or behind the dash to turn it off. maybe someone else can help more.
