Vehicle Emissions Inspection Type and Certified Analyzers

Descriptions of the vehicle emissions inspection and certified emissions testing analyzers used in the vehicle emissions inspection program areas.

Vehicle Emissions Inspection Type

On-Board Diagnostics (OBD): Computer system installed in a vehicle by the manufacturer which monitors the performance of the emission control equipment, fuel metering system, and ignition system. The OBD system detects malfunction or deterioration in performance of components that would cause the vehicle not to meet emissions standards. The Emissions Testing page on the Texas Department of Public Safety's website identifies the systems and components that are checked during an OBD emissions inspection.
