Determining whether or not your vehicle is a California emissions or a federal emissions vehicle is pretty straightforward. To do this, you'll want to locate your catalyst sticker under the hood of your vehicle. It'll either be actually on the bottom side of the hood, most GM vehicles have it on the air box, and other vehicles may have it along your radiator support at the front of the engine bay.
All you need to do is see, "This vehicle conforms to California regulations." That means that this vehicle is a California emissions car. Just because you're not in California or are in California doesn't necessarily mean your vehicle will be one way or the other.
Now, our F150 has it down here on the radiator's support, right at the front of the engine bay and you can see here, "This vehicle conforms to US EPA regulations." This means that this vehicle is a federal emissions.
Now, here we have two things that are a little different. Our catalyst is located on the vehicle's air box and this vehicle conforms to US EPA regulations and California regulations. If it conforms to both federal and California emissions, it's considered a California emissions vehicle.

In this video I have a couple of oxygen sensors with me. While there are some aesthetic differences here, the wire lengths are a little different, the actual body and tip of the sensor are a little different, the threads and gasket are the same, and on the other end the connections are actually the same. I can plug these into either position on our vehicle. But if I had to ask you which one's upstream and which one's downstream, you probably can't tell just from looking at them. That's true of most oxygen sensors. The way you determine whether or not an O2 sensor is upstream or downstream is all done visually.
Your oxygen sensor position can be determined relative to your catalytic convertor. As the name suggests, upstream sensors will be located upstream or ahead of, in front of, above, closer to the engine than your catalytic convertors. This means that they see the exhaust gasses first. They then go through the catalytic convertor and to the downstream oxygen sensor, which will either be located in the catalytic convertor like our vehicle here, or after the catalytic convertor to monitor the gasses coming out of the cat and make sure that it's being efficient relative to the readings of the upstream O2 sensor.
The other determination you need to make is bank one versus bank two. Determining which bank is which can be done by looking at a picture of your vehicle's firing order. Whichever bank contains cylinder one is going to be bank one, and the other one, regardless of whether or not cylinder two is in it, is going to be bank two by default. These banks are true of V engines like V8s, V6s, and flat engines like Porsches and Subarus that have individual banks.
On inline four-cylinder engines, as long as they have one exhaust manifold like a Jeep four-liter or a four-cylinder Honda engine, you'll only have one bank with an upstream and downstream O2 sensor. There will be no bank two on the engine.
On our vehicle here, this is the passenger side, which we've already determined from the firing order is bank one. We have our upstream sensor here closest to the engine ahead of the cat. Then we have our downstream or sensor two here inside of the catalytic convertor. This could also be located somewhere after the cat. Here I have my two sensors for the vehicle. While they are aesthetically different, we can now tell this is my upstream sensor because it looks just like the upstream sensor I have up there. This is my downstream sensor. Now that we know which one's which, we can order the right part, correct the problem, and fix you up right.

02 sensor looked just like the oem one. Perfect fit, plug and play.
Arrived on time and as described. Well packaged and no install problems. Would recommend.
O2 sensor for my 2005 Camry. Parts came in on time. Price was great with free shipping and also included specialty socket in that price range. Anti siege already applied to threads. So far works great. We will see how long it lasts.
Easy to replace and computer reads this sensor. Good quality for the price. I have 3,000 miles so far and still works.
My mechanic is GREAT--but it seems every time I pull into his garage, I'm out $500. Typical of modern technology, there are some things that seem like they should be difficult and expensive, but in reality are quite simple and relatively cheap to repair/replace. Air filters, Oxygen sensors, and fuses are prety good examples. 1A Auto's DIY videos made it pain-free to replace the oxygen sensor on my "old-reliable" 4 Runner. The kit even came with the special installation tool which I bet my mechanic doesn't even have. 1A Auto's great cross-referencing database, easy order and ship system, and online Videos gave me the confidence to take care of the job myself! I'm not super hands-on, but by just following the directions 1A provided in the video, I was able to get the job done! Thank you 1A Auto!
The service, quality of the product and the prompt delivery are great. Would recommend to others.
The new oxygen sensor was easy to install and an exact fit for my vehicle. The tool provided in this kit was ideal because I had the option of using a 3/8 ratchet or a wrench on this socket to remove the old sensor.
I ordered the wrong part because I wasn't sure of the fit, but A1 allowed me to return the part for a full refund and sent me the correct one.. The correct part was an exact fit and I have had no problems with it. I would recommend A1 to anyone including family and friends.
The product shipped on time and came as advertised. Although it was pain to remove the old one and install the new one but that is because of the location on my Toyota Avalon. Installation was a breeze when I somehow managed to thread it in. The install tool was a life saver though and I would highly recommend to all to get it along with the sensor since it helped me out a ton.
Good value worked and fit fine. The tool made it easy
This is the front downstream sensor for the 2005 Camry.
New hardware is not included with this item. You may be able to reuse your original hardware if it is in good condition.
Yes, this is the upstream (sensor 1) sensor for a 1999 Toyota Camry, but will not be correct if your vehicle is equipped with California emissions.
