On my 2005 Honda Element is this O2 sensor go on before or after the catalytic converter?

In recent production years, there are always at least two sensors. The Upstream sensor which checks exhaust before the CAT, and one downstream either on the catalytic converter or just after. The differential of the two readings is what determines the air/fuel mixture and any given moment in time. So, you actually have two, one is on the exhaust manifold right at the header collection point. The other is actually centered on the CAT. ALWAYS replace both. It is recommended that you use the actual Honda part as it is a wider range device than the after market offerings.

Our Suzuki's V6 has one on each bank of cylinders. It also has at least one other downstream, somewhere. I'm not yet sure exactly how our exhaust system is routed. I know we have two header pipes and two tailpipes, but whether or not there are one or two additional sensors in between (or catalytic converters, for that matter) is a question I'll have to answer when I find the time and energy to get these grumpy old bones beneath the thing. In any case, I'd check elsewhere for information on a particular car model, as this sensor is made to be used on an assortment of vehicles. Kind of like those Takata airbags that are leading to so many recalls, for Honda and many others. Best wishes. Our Suzuki's V6 has one on each bank of cylinders.

There is two one before and other after this go before catalytic converter�

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.

If your rig calls for a 13477, this IS a 13477. Also, the fitment guide says a 13477 2004 BMW 330xi (an X3). No problem. The pertinent question is whether you are after a pre or post cat sensor. Yes, the sensors before the cat are usually referred to as 'air fuel' sensors, not O2 sensors, but it's not unusual for folks to call all four sensors by the same name. The upstream (first IN line) sensors do sense oxygen, but are of a different construction/type than the downstream O2 sensors. IF you are after a 13477, this is it. I'm not sure this venue supports html..but here's a link that explains the system well: http://www.bimmerfest.com/forums/showthread.php?t=654792

Not sure. Occasionally the O2 sensor throws a code for other systems being out of spec. It's not always the sensor itself. Also on O2 sensors, get someone to clear the code. You can drive around for several cycles and it may clear on its own, if all is well. But it will take a few trips/few miles.

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.

That's exactly the sensor I ordered on Amazon and replaced the downstream oxygen sensor located under the body of my 2005 Honda Civic. It comes with connector so you do not need care about rewiring to old one

This is the first sensor before catalytic. The second O2 sensor Bosch 16373. Sorry for my English.

Find you manual and make sure if your engine is 1MZFE. BTW, there are 4 sensors in 1MZFE, this one is for the code 1135(bank 1 sensor 1) and 1155(bank 2 sensor 1)

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.

This part fixed my 96 4runner with the 3.4 liter. It had a P133 code and this fixed it. Bank 2 sensor one code wich is the 02 sensor before the catalytic converter. Hope this helps

This part is for either Bank 1 Sensor 2 or Bank 2 Sensor 2 (the sensor after the catalytic converter). Sensor 1 is the sensor that adjusts the air/fuel mix. It is before the catalytic converter and will likely be a different sensor type. Best to double check first.

I bought this part for my 2000 Civic so I'll do a check tomorrow for the numbers. That said, I live in CA and the car passed smog a few months ago after I installed it along with new oxygen sensors..

Hello, Sir; For the UPSTREAM CNG Engine the oxygen sensor part number 13117 For the UPSTREAM GAS Engine the oxygen sensor part number 15716 For the DOWNSTREAM GAS Engine the oxygen sensor part number 15717 or 15718. Thanks. Hope this information are helpful. Thanks

This is one of the sensors down stream of the catalytic converter, and yes there are two, one for each exhaust pipe before the muffler. Both downstream sensors are the same.

No. The oxygen sensor ports are not in this catalytic converter. You either need to use the factory ports or weld on new ones.

As it was explained to me #1 O2. sensor is closest, ahead of cat converter toward engine.
