I’m not the person you replied to, but it’s great for telling you why the check engine light is on. If you’re somewhere that requires emission testing: you can diagnose if you have an exhaust leak, bad O2 sensor, clogged catalytic converter, etc. Besides that: its good just to know if the check engine light can be safely ignored.
