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., California 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.
TECHNICAL INFORMATION
Tampering and Altering
Tampering is a violation of Federal

Tampering with or altering the
emission control system may increase
emissions beyond the legal limit.
Among those acts that constitute
tampering are:
• Removal or alteration of any part
of the intake, fuel, or exhaust
systems.
• Alterations that would cause the
engine to operate outside its design
parameters.
