Bad O2 sensor: Is car usable? 850 1997

posted by  someone claiming to be Ken Winston on  Fri Oct 28 16:54 CST 2011 [RELATED]

Dear fellow 850 owners:

So, there's a front and a rear oxygen sensor.
For one, will an OBD-II reader tell the difference?
More importantly, is there any mechanical problem with using a car with a bad oxygen sensor? If there is no problem, can the car just be used as normal, until it has to be fixed for inspection?
Thanks a lot,
Ken

    Generic code readers will call the front O2 sensor #1 and rear #2. It is the front that usually goes first. Either are not hard to replace, once you have the crud off the plugs and let the penetrating oil do its job on the sensor.

    A poor sensor will cause your engine to run rich. Running rich coats the plugs and the cat converter. Your engine will be harder and harder to start and after about 6 months, will refuse to run.

    Besides wasting a lot of gasoline money due to poor MPG.

    Replace it now.
