Will this sensor work on both right and left upstream or pre- cat position

I would purchase a left and a right and replace them both to be safe. It will not only avoid any confusion, but it will also guarantee better performance as most technicians will suggest to replace all O2 sensors at the same time.

The sensor itself will but I'm not sure about the connector and cable length.

Upstream on the Sentra SE-R. I installed this on my SE-R. I believe the downstream has a different connector (I haven't changed this one yet). I don't know about other vehicles. I suggest that you do as I did and go to Walker's website and do a search. This verified what Amazon stated on their website. This will save you time and more importantly frustration. I hope this helped.

Without knowing your year, make, model and engine size, I can't say for sure. However, I find the Walker website helpful for locating exhaust components and their locations: http://www.walkerexhaust.com/catalog/walker-exhaust-systems/e-catalog-lookup

There are two sensors, one for the inner zone and one for outer. Both if turned clockwise increases the sensitivity. However, an adjustment on one does affect the other if my memory serves me right.

The notes on the page say "UPSTREAM" - that would be before the catalytic converter. But, check your manual to be sure.

Yes works very well only thing i would change is make the mounting brackets for the sensor different size because they are about half inch apart so i had to modify to fit my needs

This sensor is both bank one and bank two sensor 2. Sometimes referred to as left or right, upstream and downstream. These are the downstream ones.

Thank you for contacting us, the downstream right is the position for the sensor after the catalytic converter on the passenger side of the vehicle. The Bosch 15718 is the downstream left sensor & the both upstream positions. The correct downstream right is the Bosch 15717. The Bosch 15178 has a completely different connector for Land Rover and Volvo and will not function on your vehicle.

I believe there is only one style downstream sensor and they are different style plug than the others.

Yes. This is an upstream sensor and fixed that same trouble code on our 2000 Honda Accord

You are better off replacing both and this kit will do it. I had the same issue in which I only needed one. But you are hard pressed to find just one sensor that will work. Save yourself the headache and use a kit.

It should work fine with that the sensor wires have clamps that go around the wire you want to monitor. Mine works great!

If I understand your question, you want one sensor to turn on a light and a second sensor to turn it back off. The answer would be "NO". These sensors do not have three-way capability.

will not work on any upstream location. haven't found a down stream application that actually works either, Save your money and don't buy universal when it comes to O2 sensors

Sensor 1 is bad. It's possible sensor 2 is as well but I would start with just sensor 1 because it could be reading "unknown" because the lack of a signal/data from sensor 1. You didn't specify if they were upsteam sensors (O2S11 & O2S12) or downstream after Cat (O2S21 & O2S22), but the upstream sensors are the most important cuz they control fuel trims & Air/Fuel Ratios. The downstream sensor are really only there to tell you if the Cat is good or not. I'm assuming you only have one Upstream & 1 Downstream sensor but some vehicles have more depending on exhaust setup. You may only see O2S11(Upstream 1) & O2S21(Downstream 1) or a combo of O2S11(Upstream 1), O2S12(Upstream 2) & 02S21(Downstream 1). Or even two Downstreams if you have true dual exhaust & not a Y-Pipe. You can tell if it's a upsteam or downstream sensor by the 4th character in the name coding. Example: 02S*1 * = 1:Upsteam, 2:Downstream. You can tell if it's a right or left sensor by the 5th character in the name coding. Example: 02S1* * = 1:one side, 2: other side. (Sorry can remember which one's right & which is left) Hope this helps.

you will need two that will be located before the converter and two that will be located after the converter. all four may be the same part# or the front sensors may have a different part# from the rear sensors. depends on the length of the wire coming from the sensor. that's what i usually see. hope this helps.

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.

Yes, this is upstream. If you have a SULEV emissions model this is the right part. If you have ULEV emission model then get part 234-9025.

I have a 2001 taco and both of my sensors are on the passenger side. 1 is between the engine block and the first catty converter. the 2nd (sensor 2) is between the 2 catty converters.
