I got the P0141 error code. I want to attempt to replace the sensor myself and I have a couple of questions.
I understand that there are 4 O2 sensors on my car.

Where is the bank 1 sensor 2 located?

Is the bank 1 sensor 2 the "downstream" sensor?

Thanks in advance for your help.

Hello,

Bank 1 on your vehicle is the rear bank facing the firewall.
O2 sensor 2 is the downstream sensor from the catalytic converter.
To replace the sensor, you should use an O2 sensor socket which has a special cut out for the wiring. See picture below.

Please let us know how you get along.
