Emissions Inspection Basics


Common Reasons for Failing an Emissions Test

How to Prepare for Your Emissions Inspection
To prepare for your emissions inspection, ensure your vehicle is well-maintained and that the check engine light is off. Driving the vehicle for about 30 minutes before the inspection can help warm up the engine to its normal operating temperature, which can improve test results.

Onboard Diagnostics (OBD) Analysis
An OBD test is performed to ensure that the onboard computer system of the vehicle is functioning correctly and detecting any emissions-related issues.
