What is OBD2 and Can it Save You Money on Car Repairs?

OBD2, or On-Board Diagnostics port, is a standardized system found in most vehicles manufactured after 1996. This port, often located under the dashboard on the driver’s side, acts as your car’s communication hub, providing valuable data about your vehicle’s health and performance. Understanding what OBD2 is and how it works can empower you to save money on car repairs and maintenance.

Unlocking Your Car’s Secrets: How OBD2 Works

Think of OBD2 as your car’s own personal translator. It continuously monitors various systems within your vehicle, including the engine, transmission, emissions, and more. When a potential issue arises, the OBD2 system stores a specific code corresponding to the problem.
