OBD Diagnostic Port Fuel Injection

gm Port Fuel Injection training bookgm Port Fuel Injection training book

Product ID 09-200-025

This Product Service Training 164 page book should be considered as GMs OBD I Generation III. Fuel control has always been the weak link in performance, fuel economy and emission control.

This book deals with all three types of fuel injection, port fuel injection (PFI), sequential fuel injection (SFI), and tuned port injection (TPI). Each of these has benefits for the motorist, and are tested similarly but there are some very distinct differences that the mechanic must understand. These fuel injection types are still used today on current model vehicles by every manufacturer.
