Where is the Oxygen Sensor Bank 2 sensor 1 (air fuel ratio) located?

Hello,

Bank 2 is the Front bank or Cylinders 4, 5, and 6 and the Catalytic converter is mounted directly to the exhaust manifold.

O2 sensor 1 is located on top of the exhaust manifold, see item 18 in the image below.

A good video how to replace, this one is for bank 1 sensor 1:

Thank you for the help, but I meant like finding the actual part the 02 sensor itself is right in the front of my car I just need help looking for the actual part itself. Thank you for the help though!

That is Honda part number 36531-RDV-004. Because it's a Honda I would suggest buying the OE part through a dealer. Honda's are very touchy when it comes to using aftermarket sensors.

Thank you for the help. I'm just running into this issue. I attached an image of that part, but as you can see where I circled the sensor plug is different as you can see in my original question. The sensor in my car currently doesn't have any of those white separators, would it just be better to take it to the dealer?

Hello,

The white separators on the connector plug are part of a replacement oxygen sensor.
See image 1 below.

I see you have corrosion on the pins. See image 2. How does the other, vehicle harness, side of the connector look like?

This is what the connector (attached to car) looks like, I’m completely baffled and still have not found the replacement the corrosion I’ve already cleaned off.

The white piece in that connector should come out as it isn't supposed to stay in there, it is part of the O2 side of the connection. Looks like it came apart and stuck in the harness side. That is why it looks different. The attached is what the O2 side of the connector looks like, notice the white plastic, the piece in your connector is that white piece, it broke off and stuck in the wrong side.

Hello,

Can you please elaborate why you want to replace the connector at the main engine harness? Is it damaged?

Cheers, Boris

I do not want to change the connector, rather I want to replace the 02 sensor that goes there but none will fit because of how the socket looks. I’m not sure if the white separators on the socket broke off from my o2 sensor and I should pull it out.

Yes, the white part needs to be removed. I suspect it got corroded and that caused it to fail and the plastic broke because the corrosion held it in place. Remove the white piece and then look at the socket under it.
