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.

In this video, we're going to show you how to replace the downstream oxygen sensor on this 2006 Ford Explorer. It has the 4.6 liter engine. We show you on, I believe the passenger side; driver's side's the same procedure. We hope you like the video. Please click subscribe. Check out 1AAuto.com for all your parts needs for your Explorer or whatever vehicle you might have. Here are the items you'll need for this repair.

Raise and support your vehicle with jack and jack stands. We have ours on a lift. The downstream oxygen sensors are the ones that go right into the catalytic converter. Passenger side is here and driver's side is over here. We're going to show you how to replace the passenger side one.

Follow your oxygen sensor connection up to this blue connector here. There's a tab right here. Press with your thumb and pull to disconnect. To remove your bad O2 sensor, just use a pair of pliers or a pair of wire cutters and cut the wires. That allows you to easily get a 7/8ths wrench right down and on. Many times these are in there kind of tough, so I like to use a hammer just to give it some impact. A few hits will loosen it up. Use some rust penetrant and let it sit. And then I've got it out a little bit and then put rust oil on there, rust penetrant, and now I'm actually going to thread it back in and see if I can work some down in. The old sensor is out.

Here are the old sensor from the vehicle and the new one from 1A Auto. Remove the shipping protector before installation. The connections are exactly the same. The oxygen sensors are exactly the same. The one from 1A Auto is going to be a very good replacement. It's going to fit and function just like your original. New oxygen sensors are available at 1AAuto.com.

Thread in the oxygen sensor. Use a 7/8ths wrench and use the open end to tighten it up. And then just make sure your lead goes up and the tab is down to go into the connector and plug it in and make sure it clicks.

Thanks for watching. Visit us at 1AAuto.com for quality auto parts, fast and free shipping, and the best customer service in the industry.
