Hello, I am Danny.
Just a quick question first. Is this a 2.0 or 3.0? Thanks for using 2CarPros.

Hello again.

I have attached two pictures of the O2 sensor location on the left (driver)side. The harness connector on top of engine you disconnect by hand by depressing a tab with fingers and unplug. You will need a O2 Sensor socket (available at all local auto parts stores) to unscrew from the exhaust. I have also attached a tutorial showing how to replace. Hope this helps and thanks again for using 2CarPros.

Hi Danny, after looking at the images carefully I was unable to identify the location of the bank 2 sensor 1 location after opening the hood. Do I need to take any components off to see the sensor? Thanks again

Hello again.

Since you will need to be under the vehicle to remove the sensor from the exhaust, may be easier to just trace the connector from the bottom to the top. This will be in the front of car, left (driver side) exhaust pipe. Hope this helps and again for using 2CarPros.
