Protege Smog Check Tailpipe
Part of the test they put the probe into the tailpipe.
On cars made after 1996 they also plug the test computer into the OBD-II connector under dash do the rest of the test. Every car sold in the US since that time has this connector which is standard. I have software and a cable for my laptop where I can also plug into this connector and do all sorts of things.
I had an O2 sensor go bad on my car so I used my laptop to clear the code from the computer (turning off the check-engine light) and to also verify the net one was operating properly.
