What does pgm fi mean

Based mainly on these two measurements, the system looks to its fuel mapping for the fuel delivery figure corresponding to the n and alpha of the moment.

Next, the engine makes adjustments as needed to this basic fuel delivery figure according to additional variables such as intake-port pressure, engine coolant temperature, intake-air temperature and atmospheric pressure. This process of recalculation of fuel delivery specs is repeated many times per second to ensure the correct mixture is being delivered to meet the existing conditions, and to provide optimal performance and remarkably crisp throttle response over a wide range of operating conditions.

This system uses various throttle bodies, digitally controlled injectors and 3-D control maps to meet the differing needs of various models. Source: Honda. Sign in. PGMFI light Mark Hill. Reply to author. Report message as abuse.

My brother has an 86 Honda accord lxi. If the car cranks and then dies almost immediately after, then the main relay may be to blame. The Check Engine Light is on. Its Integrated Braking System ensures a comfortable and stable riding experience.

With its Real Time Mileage Indicator, Glamour Fi gives you the power to control the mileage by displaying the fuel consumption in real-time. This ground triggers one of the PGM - FI internal relays that sends battery voltage to the fuel pump for two seconds to pressurize the fuel system. For all the conditions listed, the PGM-FI warning light on the dashboard must be on comes on and stays on. This indicates a problem in the electrical portion of the fuel injection system.

There is only one LED display. Which gives more mileage carburetor or fuel injection? Fuel injection is efficient than Carb. In a carburetor, at lower throttle position the amount of fuel is the air-fuel mixture is much higher than it should be, therefore, a certain amount of fuel is lost which affects the overall fuel economy of the vehicles. What is a fuel injector? Prev NEXT. A fuel injector is nothing but an electronically controlled valve.

It is supplied with pressurized fuel by the fuel pump in your car, and it is capable of opening and closing many times per second. What is a main relay?
