What is PGM-FI in Honda?

PGM-FI in Honda
Programmed Fuel Injection (PGM-FI) is a proprietary digital electronic multi-point injection system developed by Honda for internal combustion engines. It has been in use since the early 1980s and is utilized in Honda motorcycles, automobiles, and outboard motors.
Operation of PGM-FI
The PGM-FI system operates by constantly monitoring and assessing various engine, atmospheric, and riding conditions. It uses this data to control the quantity of fuel injected into the engine. The system determines the appropriate fuel delivery based on the engine speed (n) and the throttle angle (alpha). These two variables are used to look up the corresponding fuel delivery figure in the fuel mapping. The system then makes adjustments to this basic fuel delivery figure based on additional variables such as intake-port pressure, engine coolant temperature, intake-air temperature, and atmospheric pressure. This process of recalculating fuel delivery specifications is repeated many times per second to ensure the correct fuel-air mixture is achieved.
Benefits of PGM-FI
Honda’s PGM-FI technology offers several benefits, including improved fuel economy, reduced emissions, and enhanced engine performance. For example, motorcycles equipped with PGM-FI have shown improved fuel economy by 18% and the ability to use E20 fuel. Additionally, the system helps reduce CO2 emissions, which contributes to a cleaner environment.
Troubleshooting PGM-FI Issues
If the PGM-FI warning light comes on in a Honda vehicle, it indicates that the computer has detected a problem or a sensor has failed to report data. The stored error code can be retrieved for later analysis. It is recommended to consult a qualified technician or refer to the vehicle’s manual for specific troubleshooting steps.

Why is my PGM-FI light on?

First thing to do is check your battery cable connections and make sure they are tight. If they are then you should take the bike into a Honda dealer and let them check to see if there are any codes saved. The MIL indicator is like a Check Engine light on a car.

What does the PGM-FI relay do?

This relay controls power to the ECU, and the fuel pump. Without power to the rest of the fuel-injection system, or fuel pump, you won’t be going anywhere!

What happens when a PCM relay goes bad?

Erratic or random stuck shifting is one of the most severe PCM failure symptoms. A faulty sensor or PCM may lead to transmission damage. Whatever the PCM issue, you must take your vehicle for service immediately.

What is the top speed of the Honda PGM-FI?

192 – 195 km/h.
11.1 – 11.3 sec.
119 – 121 mph.
Acceleration, 0-60 mph. 10.5 – 10.6 sec.

What are the symptoms of a bad PGM-FI relay?

A bad main relay can cause problems like a no-start condition, unreliable vehicle ignition, an engine that won’t stay running, and an illuminated check engine light.

What is the PGM-FI warning light on a Honda Jazz?

If the PGM-FI Indicator Comes On
There is a problem with the engine control system.

When did Honda introduce PGM-FI technology?

1982
eSP integrates ACG Starter motor, reduced frictional losses with Programmed Fuel Injection(PGM-Fi). Since the World First to introduce PGM-Fi technology in 1982, Honda’s PGM-Fi technology has won the trust of over 55 million customers in ASEAN region, and is now delighting India.

What Honda models have PGM-FI?

It was first available on two models, the Accord SEi and the CRX Si. The following year, PGM-Fi was available on the Accord LXi, Prelude Si, CRX Si, and Civic Si. Currently, PGM- Fi continues to be used on the Accord, Civic Si, CRX Si, CRX HF and the 4WD Wagon.

What is the PGM-FI check system?

PGM-FI stands for Programmed Fuel Injection and has something to do with the fuel system. We will need to use a scan tool and check the system for trouble codes. Do you have a scan tool? Is a handheld computer that plugs into the vehicle to check for problems and perform diagnostic checks.
