Default o2 sensor used for wideband vs. reg o2

Is there any difference between the wideband 02 sensor and a regular one on the STi. Is it something that you can by anywhere. Just woundering because I can get 02 sensors really really cheap. Just woundering because maybe I couldjust hook up a volt reader too it and have a cheaper solution to a wideband that is 400 bucks

It's tough to tell what you're asking for in your post. Here's a couple random answers to questions you might be asking though

1) The front and rear O2 sensors on the STi are different.
2) The rear sensor is a standard oxygen sensor - it detects rich or lean and that's it.
3) The front O2 sensor is some kind of planar wideband sensor. It's a different part number on the STi than the WRX, but I don't know if there is any actual difference.
4) You can't plug a "normal" O2 or wideband sensor into the front O2 sensor harness on the STi - the way the ECU reads the sensor is not typical. Only the subaru part will work (unless someone recently released an aftermarket sensor, which I highly doubt)
5) You can probably plug any normal O2 sensor into the rear since it's just a plain heated O2 sensor.


Edit: Also, the corollary to number 4 is that you can't just tap a line on the ECU to get a "wideband" reading from the front O2 sensor because of the way the ECU reads the sensor.
