is this a front sensor or back sensor

I put it in the upstream spot but it is listed as "universal" which makes me think it would work in either position. Be aware that it is not supplied with connectors. The buyer must splice extant connectors onto the Denso sensors wiring.

o On my Toyota the heated sensor is the rear one. Heated sesors have 4 wires, others have 2. Lee

Single sensor, but they worked flawlessly. Well worth it, 2 years and no issues.

There is no "sensor".. this is just the fan.I use it to cool the engine compartment on a UTV. I have it on a standard toggle switch. no sensor.

Yes it is different. Front is wide band and is known as air fuel sensor. California configured auto is different fron national cars. I do believe the rear is sensor is for all states. Check the connection fitting closely. If connector is designed to only engage if it is correct. I was dealing with 98 rav4 national car.

Above/before and below/after the catalytic converter. I don't believe you can use the same sensor for both locations on most cars

Hi, these are the fronts. The fronts have the sensors. Thanks, Good Better Best Auto Parts Inc. 877-805-8686

From Mopar, part#56029398AB is one sensor. Some non-oem sensors come 4 to a bag, but like the previous comment said they do not work

Not a mechanic but I do what I can. Fronts are built for front. They have sensors for your abs systems as rear would not. At least on my suv. Plain and simple. They are different parts as in direct fitment.

there are a total of 4 oxygen sensors on that vehicle, 2 before the catalytic converter for fuel trim and 2 after that monitor catalyst efficiency. Although I believe the front and rear are different.

Yes, it is the photo-sensor.. Just return the item and get another.. A few of the items have quality issues.. 2 different revisions of the board.. Overall good and reliable product when you get one that works.. Do not forget to remove the outer lenses cover and silicone seal the threads. Will short-out the electronics should condensation get inside. I have 8 of the units working now for 1-1/2 years thru sub-zero to 105 degrees..

I was told that some cars had different front and rear sensors. My car had California emissions so they were different. Talk to auto parts store first.

It's the same sensor. But what I found out is the one i purchased seems to be used. The company i bought it from will say different but had to replace batteries,one didnt come with mounting plate and another had signs of being mounted once before. With all that said they work great and have no issues with sensors performance. Hope this helps?

This is one of the two sensors on a manual transmission 2002 tacoma. The other is a Denso 234-9003.

I really don't know. Mine is 2013 Expedition. Would love to know how to disconnect my front sensors as the bar sets them off.

It does detect rear. But the rear sensor isn't very big and I've never been hit from the back so I don't know how well it works.

On my car it's on/near the rear exhaust manifold within the engine bay. The 2nd sensor is on the catalytic converter. I bought a new sensor just to be safe when I had this part installed.
