    Why You Need an OBD-II Scanner

    Since 1996, all cars and light trucks sold in the U.S. have included an OBD-II port that stores trouble codes when sensors detect faults. Instead of guessing at issues or paying $100+ for a dealer scan, a handheld or Bluetooth-enabled reader lets you:

    • Identify engine, transmission, ABS, and emissions faults
    • View live engine data (RPM, coolant temp, fuel trim)
    • Clear codes after repairs to turn off the check-engine light
    • Monitor performance metrics and detect “pending” issues early

    Our Testing Criteria

    We evaluated scanners based on:

    1. Functionality: Code reading, making sense of PID data, code clearing
    2. Ease of Use: Interface clarity, connectivity (Bluetooth vs. cable)
    3. Compatibility: Coverage of OBD-II protocols, iOS/Android/Windows apps
    4. Additional Features: Freeze-frame data, system tests (EVAP, ABS)
    5. Value: Price vs. feature set and software subscriptions

    Pro Tips for Getting the Most Out of Your Scanner

    • Update firmware and apps regularly to cover new vehicle models.

    • Compare live data readings against manufacturer specs for accuracy.

    Common Pitfalls to Avoid
