^ where do you get that info? i can't seem to find it... all i see is toold to order and what not but i can't find any diagnostics.
i'd just take the car to a shop and have them rewire the sensor the correct way but it might help to know the correct voltage.

Just searched for o2 sensor and found it... major sensor reference wave forms.
I can't get the pics to load where I'm at, but it says the signal should increase immediately after depressing the accelerator pedal and decrease after releasing it.
