Oxygen sensor- How it really works

I found a video that explains exactly how an oxygen sensor works. If this is a copyright problem ignore the link and just visit the site. It is the ATS channel Subaru Wrx diagnosis. This is Bernie Thompson, really smart guy that solves hard problems. This guy can really think of stuff out of the box. Like I would of never thought of that kinda of things. I suggest anyone wanting to learn a few things to take a looksie.

Bernie is an asset to the industry, thank you for sharing.
