Default Trying to replace Bank 2, sensor 1 Air/Fuel sensor

These are key files and diagrams for anyone attempting to replace bank 2, sensor 1 O2 sensor. I will be trying to replace mine on Sunday. I'm hoping for a shortcut but either way it needs to be replaced.

Would these files also work on a 2007 IS250 RWD?

Check the condition of the wires going into the connector, those terminals can go bad and wires can be loose inside the connector.

I'm curious, did you have to remove the steering links and panels or did you find a work around?

Did you use an OEM replacement sensor?
