I was told I need the downstrem sensor for my LS400 - Is the downstream sensor?

Those threaded sensors were the upstream o2 sensors on my 4.7 tundra v8.. the downstream sensors had a bolt on each side to secure it. At least that was the case for my application.

Sorry for the late response, it will definitely work. It worked great on my 2004 LS430

Lois, it will be a few days before I get out to the cabin to check. Look for an update on Wednesday evening Jan 8 or Thursday. / P Hi Lois, The WS-04 (which I just looked at) has a sensor unit that--as shipped--is snapped into the bottom base of the unit, right next to the 9V battery compartment. In this configuration, the unit can simply be placed on the floor. The sensor unit can also be un-clipped from the unit for placement wherever you would like to put it. The sensor is connected (soldered) to the siren circuit board by an INCLUDED COILED-UP WIRE, which--according to information on the package--is 6 feet long. As shipped, that wire is tucked into the unit and out of sight. If you also want to connect the Water Siren to an external dial-out device you will need to supply your own 2-conductor 26-18 AWG wire. / Pete

This sensor works the upstream sensors closest to the manifold in the V6 models. I believe the downstream sensor requires removing the drivers seat as the plug, floorboard seal and pigtail are different. Google the replacement of the sensor and there are several videos on line.

I bought mine because the old one went bad, my cart mechanic diagnosed the problem. I read somewhere in my research that you need a special magnent to go with a "high speed" sensor. This alone will not give you more speed or power. Google your question, you should be able to find the same answer I did. Good luck! PS EASY to install and I'm a girl!

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

The sensor you are referring to is actually the switch itself. If you require an alarm, you may have to buy one and integrate it to the float switch wiring to provide the additional functionality.

upstream is the number 1 sensor it is a air fuel ratio sensor the. down stream number 2 sensor is an o2 sensor #1 is closer to engine these are different and can not be interchanged

I ended up doing both O2 sensors because it was cheaper. But less than a year later my rear cat converter is done and needs changing. I have 235,000 miles on though... I passed emission a month before the P0420 code came back, then it was my cat, so... I think the sensors were bad too... hope this helps!

you have to use the search for your car. It could be the upstream or the downstream sensor in my case it is the downstream on a 2002 chevy pickup.

Hi there. Most likely. I have a 1999 LS400 and it works great in there. I think they all have the same changer.

Hello; On my Pontiac grand prix it was located in the side of the exhaust pipe about in the area of where the drivers seat would be located. So I would call it a downstream sensor (for my 1996 Grand Prix that is).

I sent mine back because had to buy sensors separately I'm sure it would work ok for speed if leads are long enough.check out trail tech they make them also, call them very happy with mine and there sevice

The tach and general wiring should be fine. Speedometer will probably be harder but could probably be retrofitted to use a different digital speedometer sensor.

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

Hi - If you are replacing existing safety sensors, then yes. You will replace both. These safety sensors will not work for you if your machine is currently not equipped with them. Kevin

I am not sure what you mean by down stream. We used the part on a 1997 Toyota 4Runner. It replaced the oxygen sensor on the front side. The removal of the old part and installation of the new part took less than fifteen minutes. The new part works fine and we longer get the check engine code that indicated the original oxygen sensor had failed. We saved $160.00 by purchasing this part from Amazon and installing it ourselves. In fact, my grandson crawled underneath the car and did it for us. As for finding an answer to your question, you might do an Internet search for upstream vs downstream oxygen sensors for your automobile. Autozone or another auto part shop will check the check engine light code for you for free. Toyota wanted $49.00 just to tell us what code had caused the light to come on. My son did a search on the Internet to find the lowest price replacement part. We were delighted with the results. We got the part quickly and it fixed the problem.
