In the Seattle area, cars made after 2009 aren't required to have independent emissions tests - the car's ECU is trusted to give an accurate result.
To test cars made before 2009, they put a probe in the tailpipe. It's like the regulators have sold out, and gone full capture.

- toast0 8y agoDo they even look at the ECU on a car after 2009? California trusts the ECU on most cars after 2001, but they do plug into it. Seems kind of BS to me, at least there should be some randomized real testing, and if those don't look good, some models get blacklisted from ODB-II testing.
