O2 Sensor Question

O2 Sensor Question So, I'm pretty sure that I have an o2 sensor code being thrown. I was thinking. Instead of replacing it, would it be able to be cleaned with CRC Electronic Cleaner, like the MAF sensor, instead of replacing it? I don't know. Could be a dumb question, but doesn't hurt to ask, I guess. I'd rather try that than go drop $36+shipping on a new sensor.

Some other things that may cause O2 sensor codes is clogged cat, clogged injector, bad spark, or bad fuel/air mixture.
I've heard from people that you can't really clean O2 sensors to make them work again. But I never believe most people. I never tried it myself so I really don't know.
There's some good information in the following links...

Yeah, it's the o2 sensor. The guy I bought it from assured me of it. Also, since my car's an OBD1 car, I only have 2 o2 sensors and they're before the cat (even though I don't have one). Could a bad exhaust leak right in front of the o2 sensor also cause it to throw the code? Cause I've got a horrible leak at the connection from the header to the y-pipe that I need to try and get taken care of today.
