Default Bank 1 O2 Sensor

How do I locate the Bank 1 O2 sensor? My check engine light came on, I received a PA200 code. The dealer warned me that my Catalytic Converter would need replacing soon, I am either going to order an ARK HFC to go along with the ARK GRIP exhaust I have on the car now, or I may go the cheaper route and get a Berk Technology HFC.

Bank one is the passenger side. There are two O2 sensors per bank - one is in the exhaust manifold and the other is in the cat.

OP, I assume you mean the code was P2A00 which is the passenger side primary O2 sensor (Bank 1 Sensor 1). You might want to check for leaks on the intake side after the MAF sensor and exhaust leaks before the O2 sensor. There are a number of threads on here that are about this trouble code and iirc none of them required replacing the cat or O2 sensors.

You're right, P2A00. Thanks for the advice, I will definitely check those out.

Get it on a lift, odds are its an exhaust leak.

If anybody ACTUALLY needs replacement sensors, I have two denso's brand new in box from misdiagnosing then finding out my cat was cracked at the bracket.
