Let us take a look underneath first at the sensor before returning up top.

The sensor is held in by one 12mm bolt and one 12mm nut. So you will need a socket wrench with a 12mm extension.

There is also a tiny plastic piece that holds the wire here. This broke years ago on mine so I do a trick later where I pull the wire up as much as possible into the bottom of the vehicle. The sensor I bought did not come with this plastic attachment.

This sensor did take a beating from Mexico.

At the bottom of the floor at the top of the picture, you can pull the rubber plug out as shown above in the first picture and as seen from the sensor connector area underneath the carpet in the second photo.

Now, getting the sensor disconnected can be a bit of a pain.

For purposes of showing you all the area (and making it easier for me again in the future), I cut a hole in the rug (actually there is a small incision there) (see white box in the first photo) with scissors.

There will be a bit of sound deadening material you have to pull out should you choose this route.

It might also be possible to make this cut without removing the seat itself.

Not in the second to last picture there is a small white connector that hold the connector to the rest vehicle that also needs to be uncoupled.

If you see in the second photo there is a small blue dot. To the left of that dot is where you need to push down with either your finger or a flathead screwdriver to uncouple the electrical connection for the oxygen sensor.

Now it is time to install the new sensor. Here is the point where if you so choose you can use some anti-seize lubricant on the screws.

Again, you use a socket wrench with 12mm attachment to put the sensor bolt and nut in.

Then you need to squeeze the rubber piece shown into the hole at the bottom.

Now the little plastic connector that came with the first sensor was not present on the second one (as shown in the first photo of the hole area where it would go).

I merely pulled up the slack of the wire and tucked it into the bottom of the vehicle through the hole so the the wire was as tight as possible.

Where my fingers are at in the second photo, that is where you want to wrap the rugged electrical tape to seal the hole in the bottom of the rubber coupler. I also recommend wrapping the entire wire itself in rugged electrical tape the length of the wire until you get to the end where the wire meets the beginning of the metal sensor itself as shown in the last photo.

Then tuck the carpet back in, put the seat back, tighten the 14mm bolts into the floor and do not forget to put back the two electrical connections below that go underneath the front of the seat.

That is it.

Feel free to add any comments, observations, questions or updates to this thread.

Excellent write-up. Looks like a fairly easy job even removing the seat.

Have you checked the auto parts stores for a replacement snap-in wire bundle holder. Some have a strap built in and some use a zip-tie to attach the wire bundle. We have Pep Boys here and they have an entire aisle of miscellaneous items for parts that are going to break and need replacing.

Great idea. I didn't think of those small zip-ties, but that would also work. Pep Boys is my favorite of the major auto shops.

Would there be any possibility of splicing the new sensor to the old line to avoid the mini tear down?
