Customer Question

I need to replace the O2 sensor, bank 1 sensor 2. I'm just not sure how to find it after I take the engine cover off.
JA: Have you located all of the vehicle's oxygen sensors? Are the wires leading to and from each intact and in good shape?
Customer: I have not even attempted it yet, not sure where the sensors are. Looking for a good picture or diagram to locate them

Hi, welcome to Just Answer. I’m Ron and I’ll be helping you
Before we get started though, Please understand that I don't know
your skill level or tools you have to assist us. Also understand that
I can't see, smell, hear, or touch the vehicle either, so patience is
appreciated. JA is a great Q/A site, but it does NOT replace a
repair shop.
My goal is to make you happy and get a great rating in return for
my time. Sometimes I have to give you bad news that I know you
didn’t want to hear, so please don’t shoot the messenger.

It's under the car in back of the bank one catalytic converter.

Thanks, Ron
