i was just curious what makes a o2 sensor wideband. i heard that the new K series have wideband built in them but is it the o2 sensor itself or is it the o2 sensor and a program within the ECU

 

normal O2 sensors work from 0 - 1 volt, whereas the wideband works from 0 - 5 volts giving you a more percise air fuel reading. thats just the outputs atleast...now if theres a difference with the heater and all that good stuff im not too sure. hope this somewhat vague response helps out

edit: it would be the O2 sensor itself, and im sure the ecu would be somewhat special to take into account more accurate output.

 

OK well if i was to put a wide band o2 sensor off an 03 accord on my 92 do you think it would work and allow the use of an air fuel ratio gauge ... iv heard they don't work unless you have a wide band o2. or is this something that im just going to have to try

 

they wont be as accurate, but yes. the O2 wideband will usually emulate a narrow band O2 sensor so that you can still use it with your ECU. friend runs a narrowband with his A/F gauge and it works..just isnt all that accurate.

 

a wideband sensor alone wont do you any good, you need the controller to make it work and output a signal, but if ur talking about a stock one, that controller would be built into the ecu.

 

no it wont work unless the ecu knows how to read the 0-5 volt range.

Just by taking a wide band factory sensor off of the 03" accord and installing it on your car won't do you any good. The gauge you are talking about only see's narrow band. You would need to get something like the AEM uego or another type of stand alone wid band O2 sensor to have it work correctly.
