Anyone have a O2 Sensor they would like to sell? I thought I would throw it out there and see. I called Honda today and they want around $450 to have one installed.

 

I learned the hard way these are discrete parts. Do you need a primary (P0: header) or a secondary (P1: catalyst)?

It's the P1 secondary. I installed a cat back exhaust and as soon as I sarted the car I got the check engine light. I have reset it and it comes on everytime. I had Auto Zone hook up a code reader and it said that it was the secondary O2, Honda wanted $89 just to hook it up for me, Auto Zone did it for free.
