OBD2 readers from AutoZone can help you quickly diagnose car problems. These tools access your vehicle’s On-Board Diagnostics (OBD) system to identify error codes, saving you time and money on repairs. When your check engine light illuminates, an OBD2 reader can pinpoint the issue.
A malfunctioning vehicle is frustrating, and waiting for a mechanic can be even more so. AutoZone offers a range of OBD2 code readers and diagnostic tools to empower you to diagnose car problems yourself. Our selection ensures you’ll find the right tool for your specific vehicle make and model.
Code readers work by retrieving diagnostic trouble codes from your car’s OBD system. This system continuously monitors various engine sensors, including temperature, fuel, and oxygen levels. The data collected is sent to your car’s computer, which can detect malfunctions. When a problem is identified, the computer generates a diagnostic trouble code and triggers the check engine light. Your OBD2 reader then translates this code into a readable format, indicating the source of the issue.
Whether you need an OBD2 reader for a Ford Mustang, a Toyota Tacoma, or a Honda Accord, AutoZone has the right tool for you. We offer a variety of readers to suit different needs and budgets.
