Wideband vs regular o2 sensor..

[skilzz]

ive never understood the difference between these two

there Is SO much information out there about this, a simple search could get you answers much faster. A wide band o2 can accurately measure afrs over a wide range, much wider than you need to tune our motors. a "regular" o2 can only measure right around 14.7. I believe that the standard range for a "regular" o2 sensor is 14-15 afr. your motor runs out of this range so you can't use this to tune, it also isn't that accurate from what I understand. also a "regular" or narrowband has an output of 0-1 volts while widebands usually have a 0-5 volt output.

A wideband has a linear output. They can read from 0-5 volts.


A narrow band(stock o2 in most vehicles) is not linear. They can only read 0-1 volts.


As mentioned by dpsharp, they're reading range is from 14:1-15:1 AFR. Anything above or beyond they don't recognize.

The reason they aren't accurate is because whenever it reads out of it's zone, then it adds or decreases too much fuel to get back into its available reading range.

If there's something you don't understand from any of these posts, research it.
