Is this the upstream or downstream sensor for the 2004 Toyota Sequoia?

On my 2000 Toyota Tundra V8, it was the upstream sensor. If the Sequoia has a 4.7L V8, it is probably the same.

on my 2000 tundra..it's located before catalytic converter ..But I'm not sure on sequoia

Upstream sensors are located before your catalytic converter and downstream are located after the converter. Using the diagrams in the repair help section on autozone.com can help a lot.

You should have 4 total, 2 upstream and 2 downstream. Sensor 1 is upstream, sensor 2 is downstream. Bank 1 is drivers side bank 2 is passenger side I think

Cody Chase response is incorrect. I also have a Mitsubishi eclipse RS and it is a UPSTREAM sensor (before the catalytic converter). I purchased this product and installed it myself. Fuel economy improved

Single sensor. Put mine in about 2-3 years ago and no issues since. Took approx 1 hr for me and a friend to change in the driveway. Mine were rusted pretty severely. Biggest issue was getting the wiring disconnected without breaking the connectors.

This is the upstream sensor located in the engine bay going into the exhaust manifold. The downstream is a different model located by the catalytic converter.

2000 Ford f150 5.4L regular gas This part number 15717 is specified for the downstream; bank 1&2, sensor 2 in both cases. Part number 15716 is for the upstream sensors(sensor 1), either bank. These are original spec, exact fit, california approved O2 sensors. They do an excellent job. The downstream sensors can be replaced with a standard box or open end wrench. (I forget the size, 7/8 I think) very easy, takes all of 5 mins each. The upstream are in a much tighter space, especially the passenger side. Passenger side btw is the number 1 bank. Driver side is the number 2 bank. I highly recommend you get the short offset O2 sensor socket wrench. Powerbuilt 648691 Oxygen Sensor Offset Puller or something like it.

I'm not sure if this is for the downstream o2 sensor. Maybe someone else can chime in on that. It's bank 1 sensor 1 near the firewall and you can also use this on the manifold towards the front bumper. They are the same. Yes. This one comes with the wire and plug. Once you are able to break them loose installation is easy.

Richard,You have to do some research about the sensors that your car is using, in my case (Mazda Tribute 04) uses one upstream and one down with the same Bosh Sensor model.

According to this link, same pn, it does, and the one I received had the sensor. http://www.rockauto.com/catalog/moreinfo.php?pk=1119273

This Oxygen Sensor is a universal part that can be installed either downstream or upstream. Please be advised that this requires minor modifications.

I suppose it depends on the vehicle, but in my 1998 Jeep Wrangler TJ, this is the upstream sensor. The downstream sensor is different, and its part number is Bosch 13138, though if you're buying for a Jeep I would recommend you stay away from from the Bosch and go with NTK/NGK. I've been much happier since I switched.

No the upstream (first) O2 Sensor should fit in this header. The downstream (second) sensor is already installed before your other catalytic converter. In order to prevent a check engine light I suggest moving the downstream sensor behind the second catalytic converter if you're buying this header.

15732 = Downstream sensor15733= Upstream sensorI believe you will need 1 sensor per bank

On a Toyota Sequoia this part is for Sensor 1 on both Bank 1 and 2. Sensor 1 is closest to the engine and a bitch to remove. Borrow a special wrench from Autozone for free. They were also able to tell me exactly which sensor to replace and the part so I could buy it for half off here on Amazon.

Yes the one I ordered was downstream. Dont forget to get an oxygen sensor socket as well.usually $20 but your parts store might have a loaner program that has one in their inventory.

This sensor can be used with the left and/or right upstream on the 4.0L and 4.6L Explorer engines for 2004 based on our factory service information from AllData. You will need to cut and splice the wires as is typical for this universal replacement.
