The CAA [Clean Air Act] prohibits anyone from tampering with an emission control device on a motor vehicle by removing it or making it inoperable prior to or after the sale or delivery to the buyer. A vehicle’s emission control system is designed to limit emissions of harmful pollutants from vehicles or engines.
