An OBD2 gauge is a diagnostic tool that connects to a vehicle's onboard diagnostics (OBD-II) port to monitor and display real-time data about the car's performance and health. It provides information such as engine RPM, fuel efficiency, coolant temperature, and trouble codes, helping users identify and troubleshoot potential issues. This tool is especially useful for car enthusiasts and mechanics who want to keep track of vehicle diagnostics and maintenance needs.
