obd 2 o2 sensor question???!!!
i have a 99 si and i need to know if i could use an o2 from like a dx for the same application. do these run at different voltages? is the si a specific o2 sensor before the cat? any help will be greatly appreciated.

02s ALL run at the same voltage. 0-5V scale. This is because the voltage depends on how rich/lean you are running. The sensor itself is an output. So you could even use a sensor from a chevy or a nissan or ferrari if it fits. The DX O2 sensor will work fine.

No they don't. Most Honda O2's (at least the older cars) have a 0-1 volt range, with a few exceptions. Not all manufacturers use sensors with the same voltage range.

you're right you're right. I dont know why i typed 0-5V. There's not very many variations from the 0-1 volt range, though. Especially OBD2. Everything became pretty standardized after OBD2.

It really depends upon the manufacture and the vehicle. Some of the newer Civics have O2 sensors with a wider voltage range, as do a number of other vehicles. As manufacturers push for greater efficiency and emissions control, there will likely be a greater move away from the very narrow-band sensors. However, you're correct in that most of the sensors have traditionally been of the 0-1 volt, narrow-band variety.
