PGM-FI SYSTEM
s
GENERAL
INFORMATION
• Use
an
electric heating element to heat the water for the
ECT
sensor inspection and keep flammable materials away from the
electric heating element. Wear protective clothing, insulated gloves and eye protection.
• A faulty PGM-FI system
is
often related to poorly connected or corroded connectors. Check those connections before
proceeding.
• The PGM-FI system is equipped with the Self-Diagnostic System (page 4-10). If the MIL blinks, follow the Self-Diagnostic
Procedures to remedy the problem.
• When checking the PGM-FI, always follow the steps
in
the troubleshooting flow chart.
• The PGM-FI system
is
provided with fail-safe function
to
secure a minimum running capability even when there
is
any trouble
in
the system. When any abnormality
is
detected by the self-diagnosis function, running capability is secured by making use of the
numerical values
of
a situation preset
in
the simulated program map.
It must
be
remembered, however, that when any abnormality
is
detected
in
fuel injector, the fail-safe function stops the engine to
protect it from damage.
• For PGM-FI system location (page 4-2).
Use a digital tester for PGM-FI system inspection.
