Where can I find the bank 1 sensor 2 on a 2004 Lexus RX330?

In a 2004 Lexus RX330, the Bank 1 Sensor 2 is positioned after the main catalytic converter. This sensor is installed on bank 1, identifying cylinders 1, 3, and 5, and functions as the downstream O2 sensor responsible for gauging the level of pollutants passing through the converter. The data collected is then transmitted to the ECU. It is crucial for the readings from this sensor to differ from those of the upstream sensor, or Bank 1 Sensor 1. If both sensors report similar readings, the ECU will trigger a "Catalyst Inefficiency" code. Should one of these sensors start to malfunction, you might notice symptoms like decreased fuel efficiency and engine misfires. Additionally, the Check Engine light will likely come on. The issue could stem from a faulty sensor itself or problematic wiring. Replacing this sensor typically costs between $450 and $640 for parts and $170 to $210 for labor.
