The emission control system is a combination of parts that are incorporated into vehicles to reduce the amount of toxic emissions exhausted by the engine. Oxygen sensors, catalytic converters, throttle actuators, etc. - all these components work together to help regulate the engine performance and efficiency as well as limit the amount of partially burned or evaporated gases to go into the atmosphere. Even if at least one of them wears out or fails to function, the whole system won’t be able to ensure neither cleaner environment nor optimal vehicle’s performance. If you’ve noticed a decrease in fuel efficiency, reduced power or unstable idle, chances are one of the emission control system components is out of order and you should replace it immediately.
