Do you have a GS300 with the inline 6 or a GS400 with a v8?
On a GS300 you can do 1 of the bank 2 sensors under the hood and the other one under the passenger side floorboard so you need to jack up the vehicle for that one and the wire runs under the passenger front carpet which is not as bad as it sounds.

O2 sensors
After driving with the check engine light on for a few days I was told my O2 sensors needed replacing but when I got the cost of the replacement sensors I decided to look into the problem personally. I found the front sensor was loose and after tightening the sensor was fine - no more check engine indications. So, please verify both electrical and mechanical connections before replacing the O2 sensors.

I have the GS300 inline 6
I brought two new O2 sensors
I've already replaced both on bank one but #1 on bank two I really couldn’t get to that easily so I ordered the small O2 sensor tool since I barely had any clearance with the longer spark plug jawn lol

I felt it under the rug as I kinda pushed up on the wire where it goes into the floor

One tip I would like to add on that o2 sensor under the passenger side floor. There is a rubber grommet in the floor and the OEM o2 sensor had excellent water protection as each of the four wires were protected very well. My Denso replacement was not like the original and there was a gap in the wiring as the grommet was just one large hole. Once I got the o2 sensor fully installed, I added some gasket maker in that grommet to protect against water entering the inside so you may want to do the same depending on how your grommet looks.

This is very true. What I do is depin the new O2 Sensor and run the wires through the OEM grommet.
