is it the same sensor for upstream and downstream?

Part # is different but then the harness differs in length. I can't tell you about the 02 itself but have installed 3 by 3 and 4 by 4 w/o any issues. Google the question to be sure.

If you go to the Denso website, there is no universal number listed for the upstream or pre-cat. After an exhaustive search on the internet, I could not come up with a universal number for the upstream part. Maybe ask different Scion or other forums where a tech could answer. I have used this part for downstream replacement and has been good for 3 years.

Probably not -- check the sensors listed for your car at the Advance Auto site...they do a good job of labeling what goes where for the difference sensors. I think the meaning of "universal" in the description of this sensor applies to the different end connectors different cars might have...because you splice this into your existing wires...NOT to universal application anywhere on a car.

This is an upstream sensor. It has a short cable and special plug that fits Nissan upstream connectors. The cable is also thick because of the high temperature of the manifold.

The upstream and downstream are different from each other. At least on the v6. Look on the AutoZone website at the bosche part #s and it will tell you what you need

It's an upstream. They're good. For my x5, I used bosch 15109 for downstream, and solve my problem. Hope this helps.

I just connected mine last night. No issues. This sensor looks identical to the Ecolink sensor I purchased last week, but connected to the hub much easier.

No. Not all are sensors. You may need one for some. It depends on what you are trying to do.

On Densoproducts.com this is a Downstream (AFTER the converter O2 sensor), OE Identical type, for a 2000 Toyota Tundra, V8, SR5, Extended Cab.

Will not work for either upstream or down stream! Upstream bosch 15717. downstream 15729.

Yes it is, sometimes it's called the oxygen sensor, both are interchangeable names. The code identifies what bank and sensor number needs to be repaired, they upstream sensors, relatively easy to change out with a sensor socket.

If this is the part to match the pic, it's the downstream sensor on my '02 Tacoma 2wd SR5

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.

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.

One model was for upstream other was for downstream. I don't remember which was which but do know I had two different models

It is the upstream sensor on most oem applications where applicable. On aftermarket applications, it is often used as a wideband sensor in a wideband kit. This sensor requires control of two independent cells and uses the pump cell amperage to determine air/fuel ratio. While many aftermarket systems output 0-5v, the sensor itself does not produce a 0-5v voltage for direct measurement.

It did mine, I got both sensors and had to splice one of them to make it longer so the connector would reach. I don't remember which one. But that was easy and it works great.

They are different. Theres the ACdelco AFS105 and AFS106 ones upstream the other downstream. I don't remember which ones which.

The correct sensor is DENSO Part # 2344138 OE StyleUpstream Right/Upstream Left
