getZ Posted May 20, 2006 Share Posted May 20, 2006 Does anybody have any info on how an O2 sensor fails. How as in what does the O2 sensor do when it is bad versus what makes it fail. I'm looking for a way to diagnose a bad O2 sensor besides replacing it. Quote Link to comment Share on other sites More sharing options...
TheNeedForZ Posted May 21, 2006 Share Posted May 21, 2006 http://en.wikipedia.org/wiki/Lambda_sensor I just found the good stuff, let's all sit down and read it together... Quote Link to comment Share on other sites More sharing options...
getZ Posted May 21, 2006 Author Share Posted May 21, 2006 Good information, but not quite what I was looking for. Is it possible for a sensor to read an offset, meaning it reads and functions but reads a consistant point or two off from another sensor?

TheNeedForZ Posted May 21, 2006 Share Posted May 21, 2006 I believe so. The auto maintenance shop that service my daily driver says sometimes the oxygen sensor gets dirty and they scrub it clean instead of wasting customer's money to get a new one.
