Default oxygen sensor voltage??
i have just got a turbo timer which reads oxygen sensor voltage. just wondering what it should be for a standard green top sierra cosworth. it reads appx .12 to .14 most of the time.

monitoring narrowband voltage is a waste of time. That's is mostly just for novelty value.

And 0.12-0.14 what ?

If volts, then something isnt right with how you've wired it up.

im sure they scan up and down from 0-5volts,think the white wire is the heater wire,
so 0-5 volts scanning meaning rich-lean.
i think.....

Yep 0-1v input to ecu then the ecu converts it to 0-5v internally, go figure
