is the 2 upstream sensors the same as the down stream
823120
The two in front of CV same the two behind the CV are different... So you need two for front two for rear... 4total 2types...

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

Wayne, On my specific application the oxygen sensor where all the same the two upstream sensors (before the Cat)as well as the two down stream sensors (after the Cat). You should stick with the OEM recommendation and buy the correct oxygen sensor for your application and its specific location. Your local part house should be able to help you with making the correct choices.

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

unlikely. I replaced both on my truck they had different plugs. but on some vehicles it may be the same. I would highly recommend checking the part # for the sensor you are looking for.

Normaly the bank 1 and bank 2 sensors are the same they are the upstream sensors before the catalactic converter and the down stream sensor is after the catgalactic converter and is usually different.

In the couple of cars I'm familiar with the upstream and the downstream sensors are different.

Yes this is a "front stream" sensor. High quality with proper OEM connector. Easy installation and works great.

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.

This my friend in the pic is the up stream sensor. It is extra long and comes with the new clips to secure the wire. Hope this helps. You may also need the little round sensor remover to make the job easier.

No, the same input only. The next model up with 3 outputs can have different sources on different outputs though.

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

This one is for bank 1(closest to firewall), which I believe is also known as the downstream A/F sensor.

Yes the add on sensor has the same hardware as the original sensor shipped with the receiver.

MANUFACTURER ANSWER:Thanks for posting your question here, ck001! Both ports on the 2 port hub share the available power from the one upstream port.If you need any additional information, please do feel free to shoot us an email at support@plugable.com. We are here to help!Thanks!Regards,RozePlugable Technologies

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

You do not need to purchase two. If your system only has one sensor that's all you need. In my case, the water sensor failed and this item replaced it perfectly. My system's original air sensor is still working fine and I expect it will for a long time as it is sheltered from the elements.

no this isnt. this is the upstream for the 1mz v6. there are two of the upstreams. i am unsure if your downstream wires in to the cabin like our sienna does

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

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.

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.

Hi,Great question. The second wire is the water temperature sensor. Since this is a shoot through hull transducer, there has to be another sensor to contact the water directly to acquire a good temp reading. We have several in stock for immediate shipment
