Hello,
I'm having trouble finding the part # for the bank 1 sensor 1 oxygen sensor. Is it an upstream sensor?
Could someone also post a picture or a diagram of its location in the vehicle?
Thank you!

Dont need a part number there is no oxygen sensor that your referring to. It's a fuel air ratio sensor, likely why you cannot find the part. Buy only Denso part, look it up as 2008 CRV Fuel Air Ratio sensor IIRC and can find it easily

What about Genuine Honda part? Is Denso better?

Denso (or NGK) was probably the OEM manufacturer. DENSO 2349062 ~$100 at Rock Auto.



The wide-band sensor that Tigris accurately describes is usually called an upstream O2 sensor.

Thanks! So it is an oxygen sensor. Tigris99 said there was no oxygen sensor.

Likely last time he dealt with it, they called it that. This happens with some parts, like car buff said, usually called O2 sensor.
Just did a quick search, we're talking same part. Oxygen/Air-Fuel Ratio Sensor

FWIW, folks that try the cheaper Bosch alternates often have issues later. They were not wide band.

Easy way to remember is B1 S1 is a A/F Sensor (costs more) and B1 S2 is a 02 sensor.
