Are upstream and downstream the same for 2000 GMC Jimmy?

I can't speak for your car but as I understand it, upstream is the sensor closest to or before the catalytic converter and others after that are referred to as downstream. Sensors after the cat are not very important and although they might turn on the "check engine" light, they will have no effect on the engine performance, they simply measure emissions. I know some in the know will solder a resistor in to negate the unit so it won't turn the light on. The upstream sensor is the important one. It would seem to me that if the connectors going to the sensor are the same colors then I would install the same sensor whether upstream or downstream. If the wire colors are different, then I would assume that the sensors are different. Hope this helps and good luck. Bob

I had just commented that mine DID have a reverse flow switch, but I was referencing the 25516, not the 25517, sorry. I have since deleted my previous comment.

I am pretty sure the Bosch 15716 is for the Ranger downstream only, not upstream.

This is the upstream sensor located in the engine bay going into the exhaust manifold. The downstream is a different model located by the catalytic converter.

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).

Will not work for either upstream or down stream! Upstream bosch 15717. downstream 15729.

items are similars,but 15716 is short arness wire (20 cms.long of wire aprox.) 15717(30 cms.) 15718 is longer wire,(aprox 35cms.) My Ford F150 use 15716 upstream and 15717 dawnstream.

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

Yes it is, sometimes it's called the oxygen sensor, both are interchangeable names. The code identifies what bank and sensor number needs to be repaired, they upstream sensors, relatively easy to change out with a sensor socket.

I believe it is up stream . the catalytic converter was towards the rear as i replaced the sensor.

Yes there is if you look at the connector on them you will see one is a 4 prong male and one is 4 prong female also it should say witch is upstream and down stream ,have a look at your old ones BEFORE you order.save your self trouble by making sure you get the right one the first time

Mine was an ''02 Camry. Best to crawl underneath an find them. That is what I needed to do. I had 2 downstream. I changed both as they were the originals.

This is downstream. On mine, it was right after the cat. Plugged right in. Worked perfectly.

i got it in october 2013 but if memory serves me correctly it is a perfect fit and it is upstream. It goes in the front in or next to the cat converter. I only paid 56 dollars at that time for it. I also did 2 on a 2004 dodge neon around the same time so i hope memory serves me correctly.

Yes. It is called the downstream sensor since it is after (down the exhaust stream from) the catalytic converter

Your best bet is to go to a web site like Advance auto or similar and see if they show this part fore either up or down stream or both.

I buy this for my 2003 Honda CR-V LX and now chick ingin come on and it say O2 sincer upstream need to be replce Is this upstream for Honda crv 2003 LX ??
