Catalyst System Efficiency

Catalyst efficiency is below threshold. Common causes: aged catalyst, faulty O2 sensor or exhaust leak.

Three steps to your first scan

  1. 1. Install from Google Play

    Tap the button below or scan the QR code with your phone camera — Google Play will open the app page. Standard install, no "unknown sources" flag required.

  2. 2. Get an ELM327 adapter

    Any Bluetooth Classic ELM327 v1.5+ adapter works — starting around $10 retail. We don't sell adapters ourselves; verified models and the Bluetooth Classic vs BLE difference are documented.

  3. 3. Pair and scan

    Turn ignition on, plug the adapter into the OBD-II port, pair over Bluetooth, and tap "Scan DTC". Read operations (Mode 01/03/09) are fully passive — safe by design.
