Gasoline Direct Injection Operation and Diagnostics

GDI vehicles are common in today’s service bays. This class will focus on the high-pressure fuel system. Using a case study format, the two primary areas which will be covered are the high-pressure fuel pump and the highpressure fuel injectors. A strong emphasis will be placed on scan data interpretation. Scope data will also be used to support scan tool data.
