how long are O2 Sensors supposed to last? ..............................

If you buy a NEW car, I think federal law says that you get a free new one(O2 sensor) at 80,000 miles, so I would guess that any replacement ought to last about that long.
In all fairness there may be conditions that may shorten the life of the sensor, but I haven't specificaly heard about them.
Of course, if your shop threw an O2 sensor in when maybe it was a wiring fault instead of a bad sensor, that might account for the apparent need for a new one ?

As for the labor, it appears to be about as complicated as changing a spark plug, except that you are working on the exhaust where the heat may hold it in nice and tight and make getting the old one out a bit more effort. Wouldn't expect it to be more than half an hour for an actual mechanic to do it.


but I have been wrong before
