(Page 1 of 2) State of California AIR RESOURCES BOARD EXECUTIVE ORDER D—471—1 Relating to Exemptions Under Section 27156 of the Vehicle Code GRANATELLI MOTORSPORTS Mass Airflow Sensor Pursuant to the authority vested in the Air Resources Board by Section 27156 of the Vehicle Code; and Pursuant to the authority vested in the undersigned by Section 39515 and Section 39516 of the Health and Safety Code and Executive Order G—45—9; IT IS ORDERED AND RESOLVED: That the installation of the Mass Airflow Sensor, manufactured and marketed by Granatelli Motorsports, 5469 Oakdale Avenue, Woodland Hills, California 91364 has been found not to reduce the effectiveness of the applicable vehicle pollution control system and, therefore, is exempt from the prohibitions of Section 27156 of the Vehicle Code for the following Ford Motor Company vehicles listed in Exhibit A of the Executive Order. The Mass Air Flow Sensor is designed with two main parts: the sensor body and the electronics. The body is manufactured out of a one piece metal casting, it contains the inlet tube, the sensor mounting, and an outlet tube. The electronics are manufactured by the Ford Motor Company to be a stock replacement. The sensor fits in the stock location with no modifications to the vehicle‘s electrical system or intake air system. This Executive Order shall not apply to any Granatelli Motorsports Mass Airflow Sensor advertised, offered for sale, or sold with or installed on, a motor vehicle prior to orconcurrent with transfer to an ultimate purchaser. This Executive Order is valid provided that the installation instructions for the Mass Airflow Sensor will not recommend tuning the vehicle to specifications different from those of the Ford Motor Company. Changes made to the design or operating conditions of the Mass Airflow Sensor, as exempt by the Air Resources Board, which adversely affect the performance of the vehicle‘s pollution control system shall invalidate this Executive Order. Marketing of the Mass Airflow Sensor using any identification other than that shown in this Executive Order or marketing of the Mass Airflow Sensor for an application other than those listed in this Executive Order shall be prohibited unless prior approval is obtained from the Air Resources Board. Exemption of the Mass Airflow Sensor shall not be construed as exemption to sell, offer for sale, or advertise any component of the kit as an individual device. This Executive Order is granted based on an engineering evaluation and an On Board Diagnostic II (OBD II) testing conducted on a 1999 Ford 4.6L truck, certified to a Low Emission Vehicle standard. Test data showed that the Mass Airflow Sensor when installed on the vehicle did not affect the vehicle‘s ability to perform its OBD II monitoring. *
