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 Thanks.

In this video, we're going to replace the downstream oxygen sensor. It's the sensor that's after the catalytic converter in the exhaust. You'll need a jack and jack stands; you are going to want to raise up the front of the car and support it. After that, you'll just need a 7/8 inch, open end wrench to do this repair.

Here's a little perspective shot going from the back of the car. You want to raise and support your vehicle with jack stands and you can go right up and the oxygen sensor is right there. The connector is actually, right over here. It's a little hard to film but there's a blue safety lanyard that you want to pull out of the connector, first. Then there's a tab to pull back on and pull your connector apart. Now, we're going to use a 7/8 inch, open end wrench to put up in there. Get the right angle on it. You should be able to break the oxygen sensor free. Actually, once it comes free, they actually, usually come out fairly easily.

Put the new oxygen sensor in place and you can tell we're not actually not putting a new one in this car. There's nothing wrong with the original one, so we're usually not ones to waste a new part where a car doesn't need it. We just wanted to do this to show you, but you put it back in. You just have to work with the harness a little bit and get it finger tight as well as you can. Put your 7/8 inch wrench back on there and tighten it up. Now, you're probably going to find that aside from jacking up and putting the car on jack stands, that the most interesting part of this repair is just trying to get the connector, reconnected and especially since we're trying to film with one hand and do the connection with the other hand, makes it a little more difficult, but reconnect the connector. Put it back into its clip and also put that blue safety clip back in.
