This is one of the noobiest questions I've asked in a while but I couldn't find the info searching:

For those of us with wideband o2 gauges, do we have THREE O2 sensors?

ie, one in the o2 housing, one pre-cat that we use for the measurement, and one post-cat for emissions?

I recently blew some oil through the exhaust, and I'm looking to replace the O2 sensor that the wideband uses - I guess both the o2 sensor in the downpipe and the one post-cat are "downstream" o2 sensors? Or did those of us who bought widebands have an o2 sensor come with them, and I should buy that same model -

Thanks

edit: I think I've found my answer: wideband gauges use a wideband o2 sensor like the Bosch LSU 4.2 sensor, which is separate from the regular o2 sensors.... i believe. I think the autometer came with the bosch lsu 4.2, so I'll probably grab one of those


can anyone confirm the part number for the bosch wide-band o2 sensor that comes with the autometer 4378? i checked everywhere but I can't find it either 17014 (typical for other wideband gauges) or 17070


Answered: Most likely is the 17070 - http://www.amazon.com/Auto-Meter-224...5064631&sr=8-1

great - is the Bosch LSU 4.2 sensor universal? ie the same one that plugs into the innovate widebands will plug into my autometer, and aem?

Yup, it's the Bosch - http://www.autometer.com/tech_faq_an...x?sid=1&qid=48

I'm just checking to see if the connector portion of all Bosch LSU 4.2's are the same

It looks like the connectors can be different for different widebands... searching...

Looks like it wont matter tho, they sell those sensors with each brand.

Looks like the Bosch LSU 4.2 can have the part number 17014, which is typical (and cheap) and 17070 which is a little rarer and more expensive - and it's possible that that's the connector the autometer wideband uses
