For an emissions test, there are very few shops that will let a car slide with a pending or actual DTC present. Like jpkirk noted, even if you clear the code before you go in, not all of the system monitors will be in a "ready" status, which means the analyzer will show that the vehicle cannot be tested at that time. My father is an Emissions Compliance Officer and oversees dozens of shops to ensure that they don't pass cars that should fail.

FWIW, newer analyzer software is coming out soon that will be able to see if you've flashed the ECM recently and also if you've disabled things like aft O2 sensors or any other emissions related equipment so that you don't throw a DTC. You all have been warned!
