1. Determining Your Emissions Specification
Open your hood
Locate your catalyst sticker
If the sticker says "This vehicle conforms to California regulations," you have a California emissions vehicle
If the sticker says "This vehicle conforms to US EPA regulations," you have a federal emissions vehicle
If the sticker lists both EPA and California regulations, you have a California emissions vehicle
Hi, I'm Mike from 1A Auto. We've been selling auto parts for over 30 years. We're dedicated to delivering quality auto parts, expert customer service, fast and free shipping, all backed by our 100% satisfaction guarantee. Visit us at 1AAuto.com, your trusted source for quality auto parts.
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.
Thanks for watching. Visit us at 1AAuto.com for quality auto parts, fast and free shipping, and the best customer service in the industry.

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 an O2 Sensor on this 2006 Jeep Liberty with a 3.7 Liter V6 Engine, and both upstream and downstream O2 sensors are actually the same part and a similar process on this vehicle. We're just going to show you one of them. All you'll need for this are a new O2 sensor from 1AAuto.com, and a 7/8 inch O2 socket and ratchet or a 7/8 inch wrench.
Right here, is your bank 2 upstream O2 sensor, and here is your bank 2 downstream O2 sensor. On the other side, is your bank 1 upstream O2 sensor, and your bank 1 downstream O2 sensor, and this is the one we're going to show you the procedure on.
First, pull the harness free and then push on the tab on the connector and pull it free. For this particular O2 sensor you have a choice of which tool you can use. You can either use the O2 socket and a ratchet or you can use the 7/8 inch wrench. You really just loosen it with one of these tools and then you can remove it, the rest of the way by hand.
On the right, is the old O2 sensor. On the left, is the new one from 1 A Auto. You can see they're identical and will mount exactly the same. Twist your new O2 sensor into place and just tighten it up. Then re-clip your harness, and plug it back in. Now, you're all set.
We hope this video helps you out. Brought to you by www.1AAuto.com, your source for quality replacement parts and the best service on the Internet. Please feel free to call us toll-free, 888-844-3393. We're the company that's here for you on the Internet and in person.

Never realized what a diff a new O2 sensor makes. Engine light came on, I looked up the error code and ordered the sensor. Got here two days early and I installed it the next day. Reset computer (pulled negative battery terminal for 30 seconds) and no more engine light! Idled a bit rough at first, but a few miles later she was running like new. The install video was spot on. Very happy customer! Thanks!

Customer Q&A
Should I change only the bad o2 sensor or all o2 sensors?February 22, 2017

This is a personal preference, but in some cases once a new part is installed, other sensors may show as faulty as well because they are reading different specifications. I personally would change them all if the parts are not hard to reach to ensure a proper emissions system.
