The dealership said that I need a "downstream O2 sensor"....is this just a normal O2 sensor for a '02 GS300?

If someone could provide a link of where I could pickone up that would be helpful.


Thanks guys.

There are four O2 Sensors on the car. You will need to know which one(s) needs to be replaced.

Bank 1, Sensor 1
Bank 1, Sensor 2
Bank 2, Sensor 1
Bank 2, Sensor 2

I just replaced 2. Bank 1 sensor 2, and bank 2 sensor 2. 200$ from autozone, Bosch. You got check engine light? Search the forum, it's all on here.

Btw, Lexus quoted me 1200$$$$$$!!!!!

They are out of their minds. Took me less than 30 min to change it.

Downstream generally refers to after the catalytic converter.

I've attached a PDF from the repair manual that gives you a picture. Downstream would be 'senor 2' for both banks.

Is Bank 2 Sensor 1 the downstream sensor?. Is there a specific name for it or is it the same for the passenger side

No that is the upstream sensor. Sensor 2 are the downstream ones!

I got mine on eBay, OEM Denso units for $80. Easy to change out, less than 30 minutes.

Does anyone know the length of all the wires?
I have one but don't want to take bank 2 sensor 2 out if the one I have is too short
