Understanding OBD2 and Emissions Testing

OBD2, or On-Board Diagnostics II, is a standardized system that monitors your vehicle’s emissions and overall performance. When your check engine light comes on, an OBD2 scanner can read the diagnostic trouble codes (DTCs) stored in your vehicle’s computer, helping pinpoint the issue. For emissions testing, a cheap OBD2 scanner can help you determine if your vehicle is likely to pass before heading to the testing center. This can save you time and money by allowing you to address potential issues beforehand.

What does an OBD2 scanner do for emissions? An OBD2 scanner checks if your vehicle’s emissions systems are functioning correctly and if there are any stored trouble codes related to emissions. This preemptive check can save you a trip to the testing center.
