sorry wrong choice of words. I was trying to encourage the OP to try to learn to fish instead of begging.

Never liked fishing. Prefer to go to the market and buy it. Sometimes I will ask the butcher what is good today and he usually tells me. He never has told me to google it. Although I imagine it's because we are standing face to face and not thousands of miles apart.

But thanks to those who answered and sorry for the late thanks. I stayed away from this thread for a bit in an attempt to not get myself banned for the things I may say. But I do google things. If I ask a question it isn't without doing some research. In the end it turns out I knew what it was I just thought for some reason there was more to it so that's why I asked. It was probably my understanding of the term "wideband" that threw me off. I was thinking radio waves for some reason and couldn't relate over the air radio waves to a gauge.

 

Yea sure, but would you go to the butcher and ask him, "What's a fish?" ?

I see where you were going when you first asked this question.

You weren't far off at all... the term wideband is used the same way for radio waves as it is for a UEGO (wideband O2) sensor. When a transmitter sends out a wideband radio signal, it sends out a wide range of frequencies which allows it to carry large amounts of information. When the signal is recieved, it is then transduced into an electrical signal. The resulting transduced signal has a greater voltage spread than a narrowband signal would have, e.g. 0-12v versus 0-3v. This you already know.

A UEGO works in the same fashion, with a large range of AFRs (some sensors 10.0/1 to 20.0/1) being transduced into voltages, which have a sweep of 0-5v. The voltage value is known as lambda. A narrowband sensor can only see stoich (14.7/1), and values higher or lower. It does not determine how far away from stoich you are, just that you're either higher or lower. This is only a narrow section of the AFR spectrum, therefore the name. The voltage here only has a sweep of 0-1v.

Wideband range (general) >= ~20.0/1 to <= ~10.0/1
Narrowband range (general) >= ~15.0/1 to <= ~14.0/1

 

OP, you're NOT allowed to ask questions that people already know the answer for, didn't you know that? You jerk.
