Hey does anyone have a idea as for where the oxygen sensor bank2 sensor2 location is. I did a "search" but came up empty handed. Meanwhile since the sensor has not been working the engine light has been on and the ect button is not also working. I have a OB2 reader so i cleared the codes so the engine light goes off and the ect button still does not work. Is there any way to test this or what? Any help would be great. Thanks again.

 

First off, what car? SC300 or SC400?

 

Its an SC400.

 

OK, there are 4 o2 sensors. 2 upstream and 2 downstream. Basically that means 2 before the first cat and 2 after (1 for each exhaust manifold side). The downstream ones are easily seen on each exhaust pipe when climbing under the car. Just go under right behind the front tires and you'll see them. The upstream are a bit trickier to get to but should be easier to remove since they won't have the road grime the downstream ones have.

When under the car, follow the exhaust back towards the engine past the cat. You should be able to see the sensors on each side, if only a bit of them. It's easiest to remove the bracket that is under them to be able to get a socket and wrench in there.

Also, I used this - main sensor

and this - sub sensor

They work as a good guide but they are written for the LS.

 

Hey thanks for the info. So bank2 sensor2 should be on the passenger side...right?
