What is the PGM-FI system?
Emissions controls have become much more stringent in the US, and your Accord includes several different systems designed to control and manage these emissions. The PGM-FI system is one such. It actually combines three other systems – your fuel control, the air intake system, and your engine control system. Together, these three systems work with the powertrain control module (PCM) to manage performance, airflow, emissions production and more, including the amount of fuel injected into the engine during operation.
