Difficulty diagnosing emissions test failure without unnecessarily replacing expensive parts due to lack of diagnostic clarity.

Implied Software Gaps

• Diagnostic app that provides emissions-specific guided troubleshooting with probability-based recommendations to avoid unnecessary part replacement.

EmissiScan Diagnostics

EmissiScan is a mobile app that guides car owners through a step-by-step emissions diagnostic process. It connects to OBD-II readers, interprets trouble codes, prioritizes checks (e.g., O2 sensor vs EVAP leak), and provides a probability-based fix list — helping users avoid replacing parts unnecessarily. Unlike generic code readers, it includes emissions-specific logic and a confidence score for each potential cause.
