MVD says vehicles cannot pass emissions testing when the "Check Engine" light is on, and you should test with at least half a tank of fresh fuel.

Vehicles registered in Maricopa County cannot be tested in the Tucson area because the tests differ, but a vehicle that gets the OBD test may be tested in either area.
