Has anybody had any luck getting information about proper voltage for the front o2 sensor in a my00. I did a search and turned up a bunch of dead ends. I have a friend who may help me make an A/f meter for our wide band sensors. But I can't figure out the optimum voltage for a Stoicometric(sp) mixture. I think we might be better off reading our voltages off the wire before it gets to the ECU and is split up. Will this risk damaging the ECU? Any NEW information or help is appreciated.

Is the colour of the second O2 sensor signal white?? I connected the AF meter to that wire and it gives off some weird readings. Thx

If it's like other wide band units, it operates over a 0-5v range, not 0-1v like a traditional o2 sensor. Because of this, the wide band is pretty much incompatible with the "air fuel ratiometers" that are currently available. Hope that helps.

As much as I hate to admit it, talking to a Honda tech would probably help. Honda started the wide band O2 trend to increase efficency.
