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 rear or downstream oxygen sensor on this 2006 Chevy Impala. You'll either need a 7/8 inch oxygen sensor socket with a ratchet or breaker bar, or a 7/8 inch wrench. You'll also need a pair of pliers, jack and jack stands, and a new oxygen sensor from 1AAuto.com.
The downstream or rear oxygen sensor and harness, there, are located downstream of the catalytic converter. You can use a 7/8 inch wrench or that special O2 sensor socket that you see here. I'm using a pipe to get extra leverage. I try and break it free first with this, and if that doesn't work then I'm going to go ahead with the wrench. You can see here that I'm applying some pressure and it's just too tight. Maybe there's a little bit of corrosion between the O2 sensor and the exhaust. Before I damage the nut there, I'm going to go ahead and switch over to a traditional wrench. Now that I've broken it free, I'll go ahead and fast forward as I finish unscrewing that. Underneath the protective flashing there you'll find the connector. You'll need to first remove the little white tab that goes through the connector, so that you can then unclip it. It can be kind of tricky. You might need some needle-nose pliers to press that in. Then give it a good tug, but once you get that white little tab out, you'll be able to disconnect the connector. It won't hurt if you pull it down a little bit more, to get a little bit more room. Then lift up on the tab and disconnect the O2 sensor.
Going back in, make sure that you thread in and tighten up the oxygen sensor before you plug it in or you'll get your harness all twisted up. I'm going to use my 7/8 inch wrench again to go ahead and do that. Once I've done that I will clip in the connector there to the harness and put my little white tab back through that connector so it doesn't come loose, and then, press the protective flashing back up against the bottom of the chassis.
