DIY: O2 and Air-Fuel Sensor Removal or Renewal
 

Did you makes the video? You need to! And you have the garage to do it.

I don't think special tool 49L0-18-001 is readily available at the local Advanced Autoparts. I'd have to check.

I liked the tip about using a tap to clean the threads. But i'd like to avoid stripping the entire O2 sensor housing.

Hey Ash
I think that's a typo in the thread title ...

I think u meant removal not renewal

For being a private link, it sure is pretty sweet non the less - it gives us non-garage people a look into their world :)

Got any more vids like this ASH?

It' semantics, renew or renewal...

To renew something (in this instance) you have to remove it, so it basically means the same thing..to renew is to remove and to replace..

Done an edit, just for you.:)

I have to be somewhat careful, you never know what might pop up...

I PM'ed you...

I know this is an ancient thread, but I want to add something here since I did it yesterday on my S2 RX-8:

The service manual will ask you to remove a bunch of other stuff(the cross member of a MT model and part of the intake runner, I believe), but if you have a long enough arm and persistence(which you will need), you can jiggle your arm in between the exhaust manifold and the tranny(from below the car) and reach the connector. If your arm is thin enough, you could also reach the connector from the driver side and jiggle your arm behind the intake to reach it. Disconnecting the connector with one hand can be a pain, but it's doable.

And expect to use some WD40 to break loose the front O2/AF sensor.

The NTK part number is 24814, however, it looks very different from the OEM one. So far, I have no trouble, but NTK seems to carry one that says OE identical and it indeed looks like the OEM one I took off.

My car sometimes throws a code for running too lean, but it also smells like it's over fueling with the Cat still on and in good health. I've grown suspicious of my rear O2 sensor...

unless it’s throwing a rear O2 sensor code then the issue, assuming one exists, is elsewhere

apparently that’s not always the case as per the follow up below:

The answer was, indeed, the O2 sensor. Some time later...

it helps to be specific; the rear or front one?

Front O2 sensor

thank you.
