Can O2 Sensors go bad and not throw a code?
Like the subject says, is it possible for O2 sensors in any bank to go bad and not throw a code, if so how can you determine which ones are good and which ones aren't?

Yes. They lose the sensitivity and send inacurate signals to the ECU. You can either test them for continuity to see if they work or submerge it in water of 77 degrees or 115 degrees I believe and record the resistance readings.
