Exhaust sensor broken?

[mtnjunkie]

I took my exhaust sensor off to put in a new can. It was a pain, very tight, but I don't think I could have done anything to break it? Don't know. Anyway, the little ceramic piece that hangs down in the bottom of the sensor is broken into a couple pieces and rattling around in there. I see they are $150 new! Is this going to be a problem? Is it really necessary to replace it? I don't want to spend that kinda money on it unless I have to. I'm not sure I guess whether it monitors air fuel ratio or temp or what. Any info?

Try it and see how it runs. Don"t ever remember there being any ceramic on oxy or temp sensors though. Sure its not a build up of carbon?

I'm pretty sure. Looking into the holes in the bottom of the sensor, there are a couple pieces of white ceramic rattling around. Very thin pieces, and I can see the thin slot it fits in about 1/4" ? up from the bottom. With a piece of ceramic still in the slot. Looks like it hung down suspended in the bottom of the sensor and the bottom piece broke off. I just can't imagine why they're $150, and really don't want to spend that much on it right now. I'll see how it runs when I get it going.

the 600 sdi will show a check engine light if the exhaust sensor has failed. Start it and if you don't get a check engine light, don't sweat the small stuff.
