General OBD2 Qs - O2 Sensor Bank 0 or 1?

Hey guys,

Quick question. On my 2006 Pontiac Solstice, it's telling me that the O2 sensor on "Bank 1" has more or less failed. As a computer programmer, I have to ask, does Bank 1 mean literally... the 2nd O2 sensor, in which case the 1st O2 sensor would mean "Bank 0"? Bottom line, which one is Bank 1? I replaced the top most oxygen sensor (the one closest to the exhuast manifold) and that didn't correct my failed O2 sensor error. Before I waste my money... can someone tell me if the O2 sensor (the one furthest from the motor) is in fact the 2nd O2 sensor, and would in fact be the "Bank 1" O2 sensor?


Thanks!!!

Hah, thanks John. I confused myself so much, that I'm not sure which one you are saying yes to.


YES as in, the farthest O2 sensor is considered the 2nd O2 sensor, and is considered "Bank 1"?


Thanks! (sorry...)
