Trouble Code PO157 / BBH02S22
BBH02S22 circuit condition (heated oxygen sensor bank BB2 sensor 2)
BB2. - system running very rich or lean-check other BBcodes first.

I bought two good used oxygen sensors awhile back. They've been sitting in my room for awhile.
Should I just go ahead and replace the front two oxygen sensors?

Actually the DTC codes read as follows
Bank 1 Sensor 1 - Drivers side after manifold
Bank 2 Sensor 1 - Pass. side after manifold
Bank 1 Sensor 2 - Drivers side Heated before cat
Bank 2 Sensor 2 - Pass. Side Heated before cat
Bottom line, buy some sims or have it tuned and your problem goes away

Not hard to replace. Just need a 7/8 Open end wrench and about 30 min but the codes you have dont say anything about the front O2 sensors being bad. That's why I'm telling you to just buy the sims for the rear or tune the codes out with a basic tune anyway

I think we're having a semantics problem here. When I say front, I'm referring to the ones closest to the block - PRE-cat, not POST-cat which is closer to the muffler.

Its pretty self explanitory - You only have two sensors on each side right?
Front and Rear!
Like I said before, Just buy sims for the rear or tune them out! Problem solved!

shakky, its the rear o2's! get them deleted via tune.. it'll probably be cheaper to tune them out permanently than to replace them.
the front and rear o2's are different.

Bank 2 = Pass Side

........with tuning you can turn them off, or buy some simms.
