1st of all there's a lot of auto stores that will scan your car for free, but more than half of the time the code DOES NOT give specific clues to the problem at hand. Real Auto techs pass serious tests to diagnose emissions problems and Autozone in fact has stopped selling parts based on the code read.

Case in point we have a Toyota Sienna comes into the shop with "Catalyst inefficiency" code. This does not mean change the catalytic converter! The tech did that the code came back. They changed the intake manifold gasket, code came back, turned out to be a broken tube link on the EVAP purge solenoid! Imagine!
