Programmed Fuel Injection (PGM-FI) (Select models)

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.
