In toronto a mil light is a fail for an emission test. (don't know the legislation in your area). In the greater toronto area an IM240 test is conducted on a dyno and 5 gas analyzer. all the monitors have to run and pass.

other areas don't run dyno just check the monitors. if your area just performs the monitors check; clearing the code leaves the monitor not run which is considered a fail. You will have to clear codes then drive the car under the conditons required for the monitor to run...then the monitor will either pass (no dtc set) or fail (set dtc/ service engine soon light).

some areas give a conditional pass if you put X dollars into the repair and it still fails.

You should be able to get testing requirements from a municipal website.
