Best Answer

There are 3 Oxygen sensors on Lexus RX300.

I have replaced the 2 forwards ones so far.

The third one is Post- Catalytic converter and requires drivers seat removal to get at the electrical connector.

It is also difficult to remove the O 2 sensor from the exhaust system because it is mounted into an exhaust hanger.

How do you change 02 sensor for 1999 Lexus rx300?

There are three O2 sensors. Bank 1 Bank 2 and a down stream one. Make sure your changing the right one. Get an O2 sensor socket. After your rx is cooled down, spray penetrating oil on the threads of the bad sensor, let it soak, go inside and have lunch. When your done eating unclip the harness of the bad sensor. Use your O2 socket and turn out the old sensor. Apply anti-sieze to the threads of the new sensor and install it. Plug it back in.
