Programmed Fuel Injection (PGM-FI) (Accord, Civic, CR-V, Fit, HR-V, Odyssey, Pilot and Ridgeline)



What’s the Benefit?

This feature helps provide outstanding power and driveability, with reduced emissions and better fuel efficiency36—plus easier maintenance and repair.

 

The Feature:

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 is connected to sensors that monitor inputs such as: 
    • Throttle position 
    • Engine temperature
    • Crankshaft position
    • Intake manifold pressure
    • Atmospheric pressure
    • Exhaust-gas oxygen content
    • Intake air temperature 
  • 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. 
  • The PCM can sense when something is wrong with various parts of the system and store a trouble code, which will lead a technician to the problem area.
