TECHNICAL INFORMATION
PGM-FI System
The PGM-FI system uses sequential
multiport fuel injection. It has three
subsystems: Air Intake, Engine
Control, and Fuel Control. The
Engine Control Module (ECM) uses
various sensors to determine how
much air is going into the engine. It
then controls how much fuel to inject
under all operating conditions.
Ignition Timing Control System
The system constantly adjusts the
ignition timing, reducing the amount
of HC, CO, and NOx produced.
