DIY: Replacing air/fuel sensor

[lexus114]

And take her for a drive

[81corolla]

Put the fuse back in and start up the car. If all goes well, the CEL will be off. If the CEL comes back on:

* clean MAF
* try new air filter
* test other sensor

There you have it. How to replace the air fuel sensor. Hope this helps someone.

Nice DIY; the only thing I would add is that my hands are too big to get to the connector from above. I used this grappler gizmo ($15 @ Home Depot) from underneath.

Clip the hooks around the sensor side of the connector, reach up with one hand to open the tab and jiggle the tool with the other hand to loosen the plug; you can tell when success is at hand when the tab doesn't click back down when you let go. You can then reach up and pull out the plug.
