What should the voltage be for the O2 signal?

What should the voltage be for the O2 signal. I have a palm pilot and it is saying that it is 2.5 ruffly.

The stock narrowband sensor only outputs 0-1 volts as far as I know.

Correct, the official range is 0-1 volt. However, I've measured from -.20 up to 1.40... Typically however, mine stays between 0 and .98.

It should cycle around .5. It should go as low as .05 and as high as .95 (give or take a few).

a narrow band o2 signal should not be 2.5.. mine flucuates between .08 and .98 according to my logger.. narrow bands range from 0-1.0 v and i pretty sure wide bands typically range 1-9.9 volts depending on which wide band

Widebands are typically 0-5 volts.
