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.

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.
