The Cooperative EPA/Manufacturer I/M Test Program (CTP) was a joint effort by the Environmental Protection Agency and seven of the major domestic and imported vehicle manufacturers to recruit failed vehicles from an official state Inspection/Maintenance (I/M) program for study in a laboratory environment. The intent of the program was to gather data that could be combined with the results from a number of other studies, contributing to accomplishing several objectives. Among these were the following: Develop advice to I/M programs on improvements to preconditioning methods and formal I/M test procedures. Seek, and assess the potential of, a limited diagnosis and repair sequence as a remedy for a significant portion of the in-use emissions excess. Improve methods and models for estimating I/M effectiveness in reducing emissions. Provide feedback to the manufacturers on particular malfunction or malmaintenance types.
