B10 o2 sensor voltage readings??

[jaybirde508]

Hi forum,
Can anyone inform me as to the b10 o2 sensor voltage reading scale Ie: 0.30 = ? , 0.75 = ? I haven't been able to find this & need to know what the corrosponding values mean

Any SSM scan tool should give you the same readings -- there is no scale for the given ECU parameters. I see greater voltage swings with my O2 sensor -- all the way from 0.1v to 0.92v. The FSM (posted in the stuff you need to know forum) has the details on what are acceptable ranges.

A narrow band O2 sensor will swing back and forth between 0v and 1v. That's the way it's designed.

thanks guys I knew I wasnt explaining it rite.. what I need to know is what end of the scale is lean what end is rich I think it should go like a ohm meter & ex: 0.30 v lean & 0.75 richer ?? I'm runnning 30-32 @ idle & .75 wot & 600 to 800 in a snap So Im thinking lack of fuel??

bad FPR ?

Fuel filter?

New injectors & walbro w/less than 5000 miles

Idea's

High numbers are rich, low numbers are lean. At idle and anything other than near wide open throttle the numbers should fluctuate either sode of .45 at a steady rate and several times a minute.

At wide open throttle(or close to) the mixture should go rich and the numbers will be high and they will not fluctuate because the O2 sensor is being ignored.
