What is PGM-FI in motorcycle?

Programmed Fuel Injection, or PGMFI/PGM-FI, is the name given by Honda to a proprietary digital electronic fuel injection system for internal combustion engines with port injection. It is available since the early 1980s. This system has been implemented on motorcycles, automobiles, and outboard motors.

What is engine PGM-FI fault?

The PGM-FI light just indicates the computer detected a problem, a sensor failed to report data or something seems ‘out of bounds’ for the computer (ECU) to process. The PGM-FI light is reset during the start sequence but the stored code is not erased.

What did the Honda PGM-FI fuel mix system do?

It’s interesting to contemplate that although that particular landmark motorcycle was obviously well-known for incorporating a turbocharger to magnify the power of its 497cc V-twin engine, it was the innovation of its computer-controlled fuel-mixing system that has provided the more lasting impact.

How does Programmed Fuel Injection ( PGM-FI ) work?

Here’s how Programmed Fuel Injection (PGM-FI) works: At the heart of PGM-FI is a computer called the PCM, or powertrain control module. The PCM uses the information from these sensors to determine the fuel requirements of the engine. It then activates each fuel injector at precisely the right moment for optimum efficiency.

What kind of fuel injection does a Honda have?

While turbochargers quickly reached what seems to be an evolutionary dead-end in motorcycles, today Honda’s Programmed Fuel Injection (PGM-FI) technology has become prevalent for delivery of air/fuel mixture to the engine via high-pressure fuel injectors in a wide assortment of machines: street, dirt and ATV.

How does the fuel pump on a Honda motorcycle work?

Locating the fuel pump in the tank saves space on the motorcycle and keeps the pump cooler, preventing vapor lock. It is electrically operated and gets its power from the battery through a fuel cut relay. The Engine Control Module (ECM) controls the relay in order to operate the fuel pump.
