Hey everyone,

I have this trouble code coming up and know it’s a Circuit fault in the upstream O2 sensor heater circuit (bank 2). Located in the exhaust manifold. (Near engine)

My question is which side of the car is (bank 2) driver side or passenger side? I cannot get a clear answer on this it is not located in the Haynes repair manual that I can find and I get different answers from different people. Autozone says its passenger side the one that is a bitch to change.

Thanks in advance.

The sensors are kind of expensive I don't want to have to change both.

Could this also be the relay that powers the O2's heater?

Any links would be helpful.

if you have to replace one, replace both. i think it is the passenger but not sure. call a dealership and ask the, they might tell you
