Replacing Secondary O2 Sensor

I have an 05 Civic ex Coupe (A/T) and I'm a noob when it comes to anything more than regular maintenance, I've been looking for the secondary Oxygen sensor because the trouble code for "secondary HO2S sensor 2 slow response" popped up. Any tips? I can't find my model on youtube anywhere.

Re: Replacing Secondary O2 Sensor

Welcome to the forum.
Post moved to its own thread.

Rear sensor is in the side of the catalytic converter under the car.

I always recommend replacing with the exact same brand the factory installed in it...it will be either Denso or NTK brand.
