What does OBD II have to do with clean air?
While we have made significant achievements in improving air quality in Ohio over the last 20 years, air pollution from automobiles remains a challenge. The number of registered vehicles in Ohio has increased 125 percent since 1970, and vehicle miles traveled have steadily increased as well. Newer vehicles operate cleaner due to improved technology and sophisticated emission control systems, but these systems must be in proper working order for the vehicle emissions to remain low. When an engine is not running as designed, performance is lost, fuel is wasted and air pollution increases. OBD II can detect problems drivers do not. By detecting emissions control deterioration and/or failures, and alerting the driver to the need for attention, vehicles can be properly serviced before more serious problems develop.
