You guys still smog test 96+ vehicles? Smog machines here plug into the OBD2 port. The car either passes or fails based on if theres any codes in the computer.

New cars get a pass for the first 6 years so I had to smog my 05 Ram this year for the first time.
California will smog everything 78 and newer. All test with the sniffer in the pipe and on a dyno. If its 96 and newer they plug into the test port.
They even pressure test your gas cap and on some cars the tank itself.
So you can fail for a bad gas cap.
If the car has any kind of CEL on then they will not test it.
If its 96 and newer and the computer was reset you better put some miles on it before the test otherwise if the computer comes back with a not ready on any of its self checks you can fail.
It really sucks here.
I heard rummors about newer cars going to only the computer test in the next few years but I am not going to hold my breath.
