What Is OBD2 & Why Does It Matter?

OBD2 (On-Board Diagnostics, Second Generation) is a standardized system built into most vehicles made after 1996 that monitors engine performance and emissions. When something goes wrong, your car stores a trouble code and illuminates the check engine light. An OBD2 scanner reads these codes so you know exactly what needs attention — potentially saving you hundreds in unnecessary mechanic fees. Learn more at the U.S. EPA's official OBD resource page.
