I have a 2004 Dodge Intrepid. It's a 6 cylindar. The engine size is 2.7. The check engine light has been on and I took it to an auto parts store to see why and they said I need a new 02 sensor, but they didn't know which one was bad. The reading that printed out says:

BBHO2s12 circuit condition (heated oxygen sensor bank BB1 sensor 2)
Explanation
BBThe powertrain control module uses the oxygen sensor to calculate the air/fuel ratio in the exhaust.
Probable cause:
BB1-Oxygen sensor defective
BB2- Fuel system running very rich or lean-check other codes first
BB3- engine misfire condition-repair
BB4- Fuel pressure very high or low-fuel pump or pressure regulator

What does all this mean? I am trying to purchase the o2 sensor online, but don't know which one to choose.
I said I went to the Auto Parts store, and they said they don't know what one is bad. They gave me the print out. Read the question before you answer.
 
That is what happen when you try to get help from people that are not real mechanics. Now, the info you are giving is not correct. You need to give a code number, no a description of the code. Also is not good idea to buy and replace that 02 sensor, even if you know wich one is related to the code, because may be a wiring problem, incorrect fuel pressure, vacumm leaks, exhaust leaks, even a defective computer. My recommendation: Take the car to a real profesional mechanic.
