Hello, I’m new to this forum, so I apologize if this post is out of place (if it’s an issue, let me know and I’ll try to fix it). I took my 2006 Mazda 3 to a mechanic today to get rid of the check engine light so that it could pass smog. He told me his computer wouldn’t allow him to go any further with diagnostics, and that the problem was a faulty air/fuel sensor. He said not to get an oxygen sensor, that an air/fuel sensor is what I need. I looked online and can’t seem to find OEM air/fuel sensors and the official Mazda website seems to only carry O2 sensors (not air/fuel), does anyone know how I can find OEM air/fuel sensors?

+ He told me all of my motor mounts were worn out. I looked online and found that the Mazda3 has 3 motor mounts. Are these mounts all identical? Can I just buy 3 of the same mounts or are these three distinct parts with different part numbers?

Currently, I have these two parts in my cart. But I’m not sure if these are the parts I need.

Air/fuel sensor:

Aftermarket part suppliers call the air/fuel sensor a O2 sensor, if you look for a upstream O2 sensor, or Bank 1 sensor 1 may help.
