PGM-FI System
The PGM-FI system uses sequential
multiport fuel injection. It has two
subsystems: 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.
The U.S., Calif ornia Clean Air
Acts, and Environment Canada
EPA, California, and Canadian
regulations require all manufacturers
to furnish written instructions
describing the operation and
maintenance of emission control
systems.
The following instructions and
procedures must be followed in order
to keep the emissions from your
Honda engine within the emission
standards.
