If you just reset the PCM and try to test it will fail because some if not all the sensors aren't ready to be tested, like the O2 sensors. Those are needed for the emissions test. After restetting the PCM you have to drive the car at least 50 miles for the sensors to be ready. The only place that I can think of right now that could leak emissions would be the cat converter or exhaust.
