obd0 - obd1 4 wire o2 sensor voltage check need specs

[deftones0817]

Ok I know the voltage is in millivolts but I need to know the specs that i should be checking for. I have a black, black white green. I'm getting a code one and i just want to verify that it is a bad o2 sensor.

black - heat
black - ground
white - constant (i think) - what voltage should I have here?
green - voltage should be changing (i think) - what voltage should i have here?

Any info would be greatly appreciated. Please dont post whore and say change oxygen sensor becuase I have changed it twice. I just havent used an oem one yet. That is next after i check voltage.

i wasn't being mean, just though more people would view it here then in 4g, so hopefully resulting in more answers.

Yeah i just figured more people hang out in 4th gen and i thought that since it was obd 0 obd 1 someone might have had to check it bofore. Oh well I'll see what happens.
