Is this upstream or down stream?

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.

It is downstream you can tell by the cap for the floor board. so its under the carpet.

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.

Sorry to say I don't remember. However, the flow rate is quite good as it comes.

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

No downstream leaks here. I can't imagine what would cause that other than age and corrosion on the line.

There must be a slight gradient, but it is not apparent. Water does not pool, it drains really well.

Lenny is correct. The upstream and downstream are typically different on GM vehicles (Chevrolet, GMC, Pontiac, Buick, Oldsmobile to name a few). I never have understood why the sensors are different; externally only the electrical connectors are different, but maybe internally there's a difference...I don't know. What I usually do is use another website, typically RockAuto.com, to look up part numbers. The description will tell you UPSTREAM or DOWNSTREAM. Then I bring that part number to Amazon and see who's cheaper. Typically Amazon is since RockAuto charges shipping and sales tax (at least for me anyways; in WI). Lenny, you got lucky! I replaced all my O2 sensors on my K1500 Z71 and I'm still at 16-17mpg tops; hit 20mpg once doing 60mph for a 400mi trip.

Hello COD,The correct position is (downstream passenger right).Thank you,JohnStockWiseAuto

check the water level if it's gone down then the water must be going somewhere.

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

Inlet pressure down stream of water meter toward or connect to booster pumpThe outlet down stream of pressure pump read at 30 PSIUpstream of booster pump set at 30 PSIDown stream of the booster pump split into a three ways ??? one going to the house read more 20 PSI & the other going where???

No...it's a steady flow, nonadjustable...but it is nice :) I like it a lot!

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

sorry we are in the middle of a remodel and the contractor took it down so i've got to locate it and i'll let you know. i believe it's or its open at the other end to allow water to flow through. i'll try to locate today and let you know.

Interestingly: lower. This goes against conventional siphoning logic, but these work on a different principle. The water doesn't have to be much lower, as long as the surface of the water is slightly lower than the base of the spike you're good.

If you have the water discharge connect to a external pipe, then the connection was loose. This will be the best guess from me.

Yes it is. . . But I closed down the valve on the water line a bit -- to reduce the amount of hot water coming in -- so less was going down the drain. But it still does. Again this is normal.
