This sensor is "downstream" of the catalytic converter. On some Honda installations, this means the sensor is placed halfway down the side of the catalytic converter.

You do realize you have 4 o2 sensors on the vehicle? Obtaining a reading from its computer (failure code) will not tell you exactly which sensor is faulty. In fact, no device currently that I know of will give you an error code to exactly which o2 sensor is at fault. You may have replaced a good sensor with a new sensor and hopefully you didn't throw the old sensor out. I would put the old sensor back in and start performing the process of elimination method with the known, new sensor. Currently, you are 25% there (2 banks, 2 o2's per bank).

You should have 4 O2 sensors and it sounds to me like the wrong one was replaced. Bank 1 Sensor 2.
