Part Details
TRQ oxygen sensors are manufactured to precise specifications using premium raw materials to optimize your vehicle’s emission system. Each sensor is isostatically-pressed for improved strength and durability, and plasma-sprayed to improve sensitivity and prolong the service life of the sensors. Oxygen sensors wear out over time and should be replaced every 60,000 miles to prevent poor engine performance. TRQ recommends replacing the oxygen sensors in sets to optimize fuel economy and reduce overall emissions. All products are fit and road-tested in our Massachusetts R&D facility to ensure we deliver on our promise of Trusted Reliable Quality.

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're going to show you how to replace the left bank front or upstream O2 sensor in this 2004 Chrysler Sebring sedan. It's got the 2.7 liter V6 and it's pretty much the same operation for a 2004 through 2006. What you'll need for this repair is a new O2 sensor from 1A Auto, an O2 sensor socket and ratchet with extension, and some penetrating oil.
In order to make your job easier, 1A Auto has put together a kit with the O2 sensor socket and O2 sensor that you'll need to get this job done. You can certainly get it as the kit or you can just get the O2 sensor alone.
Locate the left bank front or upstream O2 sensor there, and the harness. You're basically going to lift up on that little tab and give it a tug. You can use some penetrating oil. I'm using my O2 sensor socket with an extension on my ratchet. I'm using a little breaker bar just because these can be tough to get off, so I'm using a pipe on the end of that to help me free that up. Once I get it free I'm just going to unscrew it until it comes out. Going back in, put your O2 sensor in place and start threading it by hand. Once you've done that you can get your special O2 sensor socket with the extension and ratchet and go ahead and tighten it up. Now you can reinstall that connector into the wiring harness.

Hi, I'm Don 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're going to show you how to replace a downstream O2 sensor on this 2004 Chrysler Sebring with the 2.7 Liter V6. This is a similar repair in a large variety of Chrysler and Dodge vehicles with the V6 engine. The only items you need for this are a new O2 sensor from 1AAuto.com, an O2 sensor socket from 1AAuto.com, or a 7/8 wrench, and penetrating oil.
Now, we sell an O2 sensor socket with the O2 sensors in a kit. You can use a 7/8 wrench, but these O2 sockets actually help quite a bit. You can see it's specially designed to accommodate the wires on the O2 sensor by having this open side. You can just use a ratchet to remove it. In some cases, using these type of sockets are the only way to actually get the O2 sensor out.
You don't need to lift your vehicle, but we do just so it's easier to show you. Here is the downstream O2 sensor we're going to change today. You want to start off just by spraying it with some penetrating oil and letting it sit for a second. Before removing that, you want to disconnect this harness right here. Using either a flat blade screwdriver, or your thumbnail, you want to push down the tab in there, and pull the harness apart. Now, using either your 7/8 inch wrench, or your O2 sensor socket, you just want to go ahead and remove that O2 sensor. We're just going to fast forward as he removes that.
You can see, on the left, is your old O2 sensor. On the right, is the new one from 1A Auto. They're identical. They'll work exactly the same and fit exactly the same. You just want to put your new O2 sensor into place and just twist it in. You just want to tighten that up with your wrench, or your socket, and then reconnect your harness. Now there it is, good as new.

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.
