is this an upstream or downstream part?

yes, this is the 2003-2007 Honda Accord Oxygen Sensor - Downstream - Denso 234-4797. OEM replacement part

No, this is the downstream one (after pre cat). It's also a pain in the ass to install, spend the exrtra and get the one with the pre-fit plug.

No, there is two different part numbers for up and down stream. Best way is to look it up on part store website, then match up the part numbers here. That's what I did.

Yup, only difference from the upstream sensor is the length of wire. Denso is the one you want

The upstream is located in the engine on the front of the car, downstream is located underneath the car maybe near the middle of the car depending on what type of car.

This is to divert the water only. It directs the water after turning it on from a separate faucet.

I've never done it, but there's a cap on the other side from the water inlet. I presume one removes this cap and makes the connection there.

I put it in the upstream spot but it is listed as "universal" which makes me think it would work in either position. Be aware that it is not supplied with connectors. The buyer must splice extant connectors onto the Denso sensors wiring.

no this isnt. this is the upstream for the 1mz v6. there are two of the upstreams. i am unsure if your downstream wires in to the cabin like our sienna does

In the couple of cars I'm familiar with the upstream and the downstream sensors are different.

slight confusion on my part... the hole in the top is the water exit (not inlet).

I removed the flow restrictor before I installed it. I think it was inside the part that attaches to the water pipe coming out of the wall. Been a while.... Handheld is not improved by this but main head is pretty nice. Love my deluge!

well it has been a while since I put mine in but as I remember there is only one place in the bottom . It is not a through flow thing it tees off of your mail line and acts like a capacitor. I think it is 3/4 pipe but it has been a while since I did the installation witch is not hard

Are you sure you have installed this correctly. It is intended as a bypass. Thus there is in a sense one one vertical direction which would correspond to the original down pipe and when not in use this is open (the top of the T in the photo) and when the divert is opened the water flows out the side. The pic should be rotated 90 degrees for the installation position. It works fine for me when in the open position the roof rain drains away but in the divert position I capture the water in my holding tank. Hope this helps.

Paddling Upstream, I hope you were notified of my answer. If not, it will be listed on this site as of now. Thanks, Chef G.

Yes, this is the downstream sensor. The upstream sensor is actually an air/fuel ration sensor and costs ~3 times more than this one.

You can divert to one or the other, or both. When you do both the water pressure is half on each side.
