It is a real pain. My suggestion is to take it to a shop.
In the Lexus IS300, the oxygen sensor for bank 2 sensor 2 is located on the exhaust system, specifically downstream of the catalytic converter on the passenger side of the vehicle. This sensor monitors the oxygen levels in the exhaust gases after they pass through the catalytic converter, helping to optimize engine performance and emissions. To access it, you may need to lift the vehicle and work from underneath, depending on the model year and any aftermarket modifications.

Trouble code P0175 means:System too rich (Bank 2)
Trouble code P0430 means: Catalyst Efficiency Below Normal (Bank 2)
It's the sensor under the passenger seat near your Y pipe. (The IS has 4 sensors.....3 near the engine, and this one) Unscrew it (VERY hard to get off) then cut the wires. Splice the wires from a new one, solder, heat shring wrap it, disconnect battery to reset ecu, and you are good to go.
