Hi, I'm Don from 1A Auto. I hope this how-to video helps you out, and the next time you need a part for your vehicle, think of 1AAuto.com. Thanks.
In this video, we're going to show you how to replace an upstream O2 sensor on this 2002 Chevy Suburban. We show you on the passenger's side, but the driver's side is a similar procedure. The items you'll need for this include a new upstream O2 sensor from 1AAuto.com, a flat blade screwdriver, 7/8 inch wrench, and a pair of wire cutters.
To start off, we're going to show you where your O2 sensors are. The driver's side is bank one and this is bank one, sensor one and bank one, sensor two. On the passenger's side, you have bank two, sensor one and bank two, sensor two. Both sensor ones are the upstreams, and both sensor twos are the downstreams. We're going to show you on bank two, sensor one.
The harness is on the other side of this frame. You just want to just clip the harness pin, pull the harness free, and disconnect it. Just pull the tab, pull it free, and then you want to pry at this clip with a flat blade screwdriver and separate it. You want to pull your O2 sensor wire free from that clip and then cut the harness connector at the end from the harness.
Two notes: this is going to allow you to get the closed end of the wrench over the harness and also you can do this without having to jack up the vehicle; the clearance is good enough on these vehicles to get underneath.
Now, using your 7/8 inch wrench, just slide it up into place on the O2 sensor, and, using another wrench for leverage, just break it free. Then loosen it up the rest of the way with the wrench and remove it. We'll just fast-forward as Don does this.
On the left is the old upstream O2 sensor; on the right is the new one from 1A Auto. You can see they're going to fit exactly the same. Feed your new upstream O2 sensor into place and just twist it in. We'll fast-forward as Don does this and then tightens it up with the wrench.
Now put your harness back over the frame and reconnect it into that clip. Then pull it over the other side, reconnect the harness, and push that pin back into place. Then re-clip the harness up here into this bracket, and you're all set.
