how do I fix a "ho2s bank 2 sensor 1" problem? can anyone tell me? thanks :-)

Need more info. What vehicle, engine, how did you determine that code? Not much to go on, but possible O2 sensor change if the mileage is high enough.

2001 Rodeo Sport Convertible 3.2L V6 and automatic transmission

I'm working on that sort of problem on my 1999 Rodeo v6 3.2 l right now. I replace all 3 o2 sensors check as much of the wiring harness as I could found no issues... I get code: P0132 I think.
