Dese the Upstream sensor require this part or is this just for the downstream, after catalytic converter sensor?

I found it useful. It also protects the O2 sensor while you are installing it. Without it you will need to be patient with an open end wrench. For the modest cost it made the job a lot easier.

O2 sensors whether up/downstream are the same size so you can use it for either. Most O2's are 7/8" in size and that's what size this tool is.

It works on both. It just made it a lot easier to remove because of the slot made in the socket for the wire. It was definitely worth it because a regular socket or box wrench just doesn't give you enough torque to remove it.

Downstream is accessible with a wrench but I've still used this tool on all four. Just so much easier and no slipping wrench and woundedd knuckles!

I'm pretty sure the answer is no. Too bad because I have one that I can't use. You need to know your engine model and then look online to figure out what sensors work. You need two one upstream and one downstream.

Hello, Sir; For the UPSTREAM CNG Engine the oxygen sensor part number 13117 For the UPSTREAM GAS Engine the oxygen sensor part number 15716 For the DOWNSTREAM GAS Engine the oxygen sensor part number 15717 or 15718. Thanks. Hope this information are helpful. Thanks

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.

Thank you for contacting us back. If you need the Oxygen sensor Before the Catalytic then you need the Upstream Oxygen sensor. The Correct Upstream sensor for your 2009 FORD ESCAPE 3.0L V6 is the Bosch 18124.Best Regards,Romer

Before you buy it, go to the denso website at densoautoparts com.You can check your fitment there to be sure the amazon information is correct.For your car, the correct upstream (before your catalytic converter) sensor is 234-9004.The correct downstream (after your catalytic converter) is 234-4122.The item you are looking at here, the 234-9005 is not the right sensor for your car.

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.

It is upstream. It attaches to the catalytic converter. It works as OEM. Mine is still running great.

Our Suzuki's V6 has one on each bank of cylinders. It also has at least one other downstream, somewhere. I'm not yet sure exactly how our exhaust system is routed. I know we have two header pipes and two tailpipes, but whether or not there are one or two additional sensors in between (or catalytic converters, for that matter) is a question I'll have to answer when I find the time and energy to get these grumpy old bones beneath the thing. In any case, I'd check elsewhere for information on a particular car model, as this sensor is made to be used on an assortment of vehicles. Kind of like those Takata airbags that are leading to so many recalls, for Honda and many others. Best wishes. Our Suzuki's V6 has one on each bank of cylinders.

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

If you have the V6, both upstream sensor should be the same. Your diagnostic code should tell you if your problem is bank 1 or 2.I only needed to replace the bank 1 sensor and that solved the issue. Check out this web page for more info, (maybe more than you need, or want). http://www.autoshop101.com/forms/h37.pdf

That part number is for 1997 Honda CRV. It is the upstream sensor which is before your catalytic converter. Please check to make sure that it the one you need. The post catalytic oxygen sensor is part number 234-4098. Hope this helps.

Yes, It is downstream, under the body of catalytic converter, after the catalytic converter. sorry for late answer. did not have time to check email earlier

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

Yes it would but you only need to replace the rear aka downstream sensor after the catalytic converter on bank 1 to clear this code but I have found the other downstream sensor in bank 2 to fail shortly thereafter so typically replace them in pairs

Correction: I was mistaken, this did not replace the upstream sensor, it didn't fit, I had to order a different item. My apologies.In my 2005 Pontiac Vibe it replaced the upstream sensor perfectly.

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
