1. What is an OBD2 Scanner and Why Do You Need One?

An OBD2 scanner is a diagnostic tool that accesses your vehicle’s On-Board Diagnostics (OBD) system, providing valuable insights into its performance and health. It’s essential because it allows you to read and clear diagnostic trouble codes (DTCs), monitor engine sensors, and identify potential issues before they escalate into costly repairs.

1.1 Understanding the OBD2 System

The OBD2 system, standardized in 1996, is designed to monitor various engine and vehicle parameters. According to the Environmental Protection Agency (EPA), OBD2 systems help reduce emissions by alerting drivers to potential issues that could affect engine performance and emissions control. An OBD2 scanner taps into this system, providing real-time data and diagnostic information.
