MULTIPORT FUEL INJECTION (MFI) DIAGNOSIS
TSB Revision
MULTIPORT FUEL INJECTION (MFI) <3.0L ENGINE>
13B-354
.
CIRCUIT OPERATION
• The injector power is supplied from the injector
relay (terminal No. 3).
• The ECM controls the injector by turning the
power transistor in the ECM "ON" and "OFF".
.
TECHNICAL DESCRIPTION
• The amount of fuel injected by the injector is con-
trolled by the amount of continuity time the coil is
grounded by the ECM.
.
DESCRIPTIONS OF MONITOR METHODS
The ECM detects open circuit and short malfunction.
.
MONITOR EXECUTION
