The On-Board Diagnostics (OBD) system is a standardized system used in modern vehicles to monitor engine performance and emissions. For Honda vehicles, understanding how OBD2 works is crucial for effective car maintenance and diagnostics.

1.1 What is OBD2?

OBD2, or On-Board Diagnostics version 2, is a standardized system that monitors a vehicle’s engine, emissions control system, and other components. According to the Environmental Protection Agency (EPA), OBD2 was mandated in all cars and light trucks sold in the United States starting in 1996 to reduce emissions. This standardization allows any OBD2 scanner to interface with any OBD2-compliant vehicle, providing access to a wealth of diagnostic information.

1.2 How Does OBD2 Work in Honda Vehicles?

In Honda vehicles, the OBD2 system employs various sensors and computers to monitor the performance of the engine, transmission, and other systems. These sensors transmit data to the car’s main computer, which interprets the information. When a problem is detected, the computer stores a Diagnostic Trouble Code (DTC) and may illuminate the Check Engine Light (CEL) on the dashboard. Using an OBD2 scanner app, you can retrieve these DTCs and gain insights into the potential issues.
