I was wondering the OE oxygen sensor for my car some say Bosch some say Denso. I just was wondering which is correct. It looked like I only have one sensor on my vehicle but if I'm wrong let me know. :)

Hi,

Denso is responsible for the manufacturing of oxygen sensors for most Honda vehicles. Here is the OEM part number, but if you look it up, it says manufactured by Honda, which isn't true. Note: The part number is for a standard Civic. The Si is different, and they are different between CA emissions and Federal emissions as well.

Oxygen sensor part number -- 36531PM8305

And yes, there is only one. It is mounted to the exhaust manifold. See pic below.

Let me know if this helps.

Take care,

Joe
