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.

Hi, I'm Mike from 1A Auto. I hope this how-to video helps you out, and next time you need parts for your vehicle, think of 1AAuto.com. Thanks.
In this video, we show you how to replace an O2 sensor on this 2011 Chevy Silverado 1500. It's the same part and a similar process on a large variety of GM models. The items you'll need is a new O2 sensor from 1AAuto.com, flat blade screwdriver, specialized 7/8 inch socket specialized for O2 sensors, ratchet, and possibly a piece of pipe for leverage.
We have the vehicle lifted. You don't actually have to do this, we just do this to make it easier to show you. Right here is your downstream O2 sensor, your catalytic converter, and your upstream O2 sensor. On the other side same thing: downstream, catalytic converter, and the upstream.
We're going to show you how to replace one of the upstream O2 sensor. Here's the 7/8 inch socket wrench, and you could use a 7/8 wrench but we recommend the socket. It will make it a lot easier.
Slide that special socket on there, attach a ratchet, and a piece of pipe for extra leverage. Once you break it free you can loosen it the rest of the way and remove it by hand. If you follow the harness from the O2 sensor you'll end up here. This will be a little bit hard to show some of this because there's not a lot of space to work there. Pry off the clip that holds this to the harness. You see that's freed.
Now, what you want to do is use a pair of pliers. You can also use your hands or a screwdriver. Pull that green pin out and then disconnect the harness. There's actually a little black clip that connects the harness. Pull that out of there. You may need a flat blade to help you pry it out.
Here's the new part up front, the old part in the back. You can see they're identical. The exact same part, all the same mounting points and everything. Feed your new O2 sensor up into place and twist it in. Fast-forward as he tightens that up. He does this at a slightly different order, but it's the same set of clips.
You want to first reconnect that wire to that harness there with that large clip. Take that little black clip and slide it into place on that bracket. Reconnect the harness and slide that green pin back into place. You're all set.

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.

In this video, we're going to replace the upstream oxygen sensor. Now that's the one that's before the catalytic converter. It's between the motor and the catalytic converter. This is a 2007 G6 with the 4 cylinder motor, same as any G6 or Saturn Aura. The only tool you'll need is a 7/8 inch, oxygen sensor socket and a flexible headed ratchet will make the job easier.
Access your upstream oxygen sensor. It's right in behind the engine. This is a 2.4 liter, 4 cylinder. There's the oxygen sensor. There's the electrical connector. Now back in, there's a blue, little safety lanyard that you need to pull out. Then, there's just a tab on top of the connector, pull it up with your thumb and then you should be able to pull the connector right off. Now grab the other end, the end that's connected to the O2 sensor and pull it out of the clip. This is the tool that makes all the difference. It's an O2 socket. See it has a big slot in it that allows the electrical connector to go out to the side and then you put the socket around the oxygen sensor. A flexible headed ratchet like this is going to be your best bet, allows you to get the most leverage. Once you get the ratchet on there, turn the O2 sensor out and actually, this one comes out fairly easily once we get it started.
The new sensor goes in, just opposite of how the old one came out. Put it in place, get it in the hole and you can usually start it in by hand. Then, once you get it fairly tightened up, then make it nice and tight with the socket. Now, obviously, we need to reconnect the oxygen sensor. I'm just going a little fast, here, because doing it with one hand, makes it a little more difficult, but reconnect the connector. Make sure you put that locking clip back into place. Then clip the connector back into the bracket.

All is good. Installed and drove for about 150 miles. Code cleared and passed smog. Glad it worked out.
Worked great on my 2005 Suburban 1500. The hardest part of the whole job was disconnecting everything. O2 sensor codes went away immediately after replacement.
I needed to replace to O2 sensor on my wife's truck. This one arrived quickly (even during the pandemic). The part worked as advertised and even came with the required tool. It was much cheaper than any of the local parts stores.
The sensor is working great and the tool worked very well for the install.
The tool help take the old sensor off and the easy to re-install
matched up right away from computer, great replacement part
Got package fast
Easy in and out with tool part was correct check engine light is off truck runs great
I installed this on a 2004 Silverado 1500 5.3L, upstream. The product fit perfect and functions as it should. I no longer have a check engine light illuminated on my dash. The only reason I would not review this product as 5-star is because the included socked was a bit flimsy. My sensor was stuck pretty good, and this socket would flex when I applied force, and rotate around the points on the sensor. I ended up buying a different style O2 socket to complete the job. I would still buy this product again, and now I have this handy socket for "less stuck" O2 sensors.
I was not able to use the tool for removal, it kept slipping off but I got it off with a pipe wrench and used the tool to install the new one and it worked just fine. My engine light does not come on any more and my truck runs great now.
Some vehicles have the same upstream and downstream sensors and others will be separate parts. You should be able to determine the fit through our vehicle fit list.
1A Auto's house brand parts are manufactured by various aftermarket companies specifically for us and built to your vehicle's exact OEM specifications.
