Default O2 sensor Bank 2 Sensor 1 replacement help

Hi Guys,

I've searched the forum for hours but can't seem to find the answer to my question. My O2 sensor (bank 2, sensor 1) which I believe is the passenger side sensor before the CAT comes up faulty on the scanner. (CEL, TSC and TSC off light is also lit) I've located the sensor but can't seem to determine where it come thru the floor/firewall into the passenger area. Do I need to remove the passenger side carpeting (and if so how?) or can I go thru the shifter area?

Thanks so much.

bank 2 sensor 1 is on the passenger side exhaust manifold. you can get to it from underneath the car with the covers removed. it is before the catalyst.
i hope this helps

Banks 1 & 2 sensor 1 wiring is in the engine compartment. Banks 1 & 2 sensor 2 wiring comes up inside the instrument panel. See the partial diagram "H15" & "H16" below.

The attached PDF shows the sensor you wrote about in the first comment.

You guys are the greatest!
Would you happen to know the universal part numbers for denso or bosch brands for all four o2 sensors?
Thanks again.
