the OBD1 ecu won't check for a secondary O2 sensor, correct.

As far as OBB2/OBD1 for emissions.

MY state (connecticut) for all vehicles after 96 (OBD2) just do a scanner test no sniffer.

Now, if they can't get the scanner working, I theorize that they'll think it's user error and just put the car on the sniffer... Joe average worker will probably just assume the computer screwed up somehow....

And you should in general pass emissions with a turbo and a cat.
