Is this for the forward bank( on the engine side of the catalytic converter?).

I have an F150 with the 5.4 engine that is positioned longitudinally, so my cylinder banks are oriented right and left. The o2 sensor on the engine side of the cat is #1 and the sensor downstream of the cat is #2. I recommend you go to the Bosch Auto Parts web site and look up your vehicle. It specified this sensor for all 4 locations on my vehicle. Yours may require different length electrical connections (wires) to connect to the #1 vs #2 cat.

"Bank 1" refers to the driver's side of the exhaust manifold/catalytic converter assembly and "Bank 2" refers to the passenger side of the assembly. Sensor 1 simply means the sensor is above/before (or upstream) the cat converter. The 2 sensors located before the cat coverter are actually air/fuel ratio sensors. The drivers side one is specified Bank 1, Sensor 1, while the pass side one is called Bank 2, sensor 1. Regardless of whether on bank 1 (dr side) or bank 2 (pass side), the same part number fits both. The 2 rear sensors are under, or downstream of the cat converter and are called Bank 1, sensor 2 and Bank 2, sensor 2. They are accessed from under the vehicle by removing the plastic behind the bumper. The part number for these 2 will also be the same, but of course different from the top 2. Here is an explanation with pictures that hopefully clears it up and you can always register on the forum and ask questions if it is not clear: http://www.rav4world.com/forums/99-4-3-mechanical/78837-p0051-bank-2-sensor-1-p0158-bank-2-sensor-2-o2-sensor-replacement-2.html

There's a pre-catalytic converter and post-catalytic converter. There's also another one near the exhaust manifold. You need to know which one they are. I would recommend you go to http://www.rockauto.com/catalog/ and find your car and the parts you might need. I sometimes buy from that site unless amazon has it cheaper.

Yes, this is the downstream sensor. The upstream sensor is actually an air/fuel ration sensor and costs ~3 times more than this one.

That is for the front and is the same for both left and right sides. Make sure you confirm that part fits your specific car.

on my 2000 tundra..it's located before catalytic converter ..But I'm not sure on sequoia

This is the right side, note you need to replace both sides for the benefit of a better ride... Good price and works great.You should replace the engine and transmission mounts also.. I am on my third set. Good Luck.

The one I bought is for natural gas. You still need to get the stainless steel exhaust pipe to install.

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

yes, but the o2 sensor should be pointed forward, bcuz it won't screw in the way it's pictured. Try looking at more options

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.

Yes it is. It acts as half of the valve body. You can swap it to one that doesn't have the nipple of you need to

Absolutely not, a catalytic converter is a fat can that sits right in front of the engine, its job is to convert some of the harmful gasses into harmless gasses. This header is a simple pipe that does no "filtering" at all. And it looks nothing like a catalytic converter. If you're in the state of California or another California emissions state this will not pass inspection. So to answer your question, no this part does not qualify in any way as a catalytic converter.

I believe it goes in with the metal part to the left (exhaust side). If it's in the wrong way, the automatic operation doesn't seem to work.

It is for the upstream location before the catalytic. Right below the exhaust manifold.

Yes. Usually it's bank #1 and bank #2 (bank one coming off the #1 cylinder). Upstream refers to the manifold side of the converter and downstream is the back side, or end towards the muffler.

There is no catalytic converter included. It does bolt up to your stock cat perfectly tho. I have a 2001 civic ex coupe and everything fits like a glove.
