Is this the Upstream or Downstream sensor?

Its a 0-5 volt sensor, which is typically used for a pre cat sensor, and for aftermarket wideband gauges.

It is the upstream sensor on most oem applications where applicable. On aftermarket applications, it is often used as a wideband sensor in a wideband kit. This sensor requires control of two independent cells and uses the pump cell amperage to determine air/fuel ratio. While many aftermarket systems output 0-5v, the sensor itself does not produce a 0-5v voltage for direct measurement.

This will not fit your car. Do you need an upstream or downstream sensor? Manual or automatic transmission? California or not?

I don't know where the sensor is, but I just experimented and can control the fan from above or below the unit. I am pleased with its performance.

Upstream sensors are located before your catalytic converter and downstream are located after the converter. Using the diagrams in the repair help section on autozone.com can help a lot.

I suppose it depends on the vehicle, but in my 1998 Jeep Wrangler TJ, this is the upstream sensor. The downstream sensor is different, and its part number is Bosch 13138, though if you're buying for a Jeep I would recommend you stay away from from the Bosch and go with NTK/NGK. I've been much happier since I switched.

I bought only the sensor. I'm on my second sensor now I got about a years use out of the first one.

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

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

If you have the V6, both upstream sensor should be the same. Your diagnostic code should tell you if your problem is bank 1 or 2.I only needed to replace the bank 1 sensor and that solved the issue. Check out this web page for more info, (maybe more than you need, or want). http://www.autoshop101.com/forms/h37.pdf

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

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.

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.

The upstream sensor threads into the pipe coming from the engine, closer to the front of the car, and the downstream sensor threads into the catalytic converter, more toward the rear of the vehicle. They are not interchangeable.

I tried using another sensor from a different set along with the sensor that came with the receiver it did not work. Sorry.

This one is placed before the Catalytic converter, on the exhaust manifold. That would be upstream.

No. I had to replace my sensor awhile back because I was getting hot water through the cold water tap. You need the sensor valve for it to work correctly.

AS far as I know it is a downstream sensor and I bought it for my 2004 Buick Century with V6 engine
