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 the downstream oxygen sensor, or the oxygen sensor that is after the catalytic converter. You'll need a jack and jack stands to raise your car and support it securely, and then you'll need a 7/8 inch tubing wrench, and then another wrench to hook on to it for some extra leverage.

Locate the downstream oxygen sensor and the connector right above it, and go ahead and press the tab and pull it free. I'm using a 7/8 inch tubing wrench, sliding it over the harness. I'm going to use an extra wrench.

I've got the new part from 1A Auto with the anti-seize that comes with it, and I'm going to spread the anti-seize just on the threads, careful not to get it on the end. Go ahead and thread the new O2 sensor in, and tighten it up. Plug your sensor back in.
