FUEL INJECTOR
DescriptionINFOID:0000000001671099
The fuel injector is a small, precise solenoid valve. When the ECM
supplies a ground to the fuel injector circuit, the coil in the fuel injec-
tor is energized. The energized coil pulls the ball valve back and
allows fuel to flow through the fuel injector into the intake manifold.
The amount of fuel injected depends upon the injection pulse dura-
tion. Pulse duration is the length of time the fuel injector remains
open. The ECM controls the injection pulse duration based on
engine fuel needs.
Component Function CheckINFOID:0000000001671100
1.INSPECTION START
Turn ignition switch to START.
Is any cylinder ignited?
YES >> GO TO 2.
NO >> Go to EC-313, "
Diagnosis Procedure".
2.CHECK FUEL INJECTOR FUNCTION
With CONSULT-III
1. Start engine.
2. Perform “POWER BALANCE” in “ACTIVE TEST” mode with CONSULT-III.
3. Make sure that each circuit produces a momentary engine speed drop.
Without CONSULT-III
1. Let engine idle.
2. Listen to each fuel injector operating sound.
Is the inspection result normal?
YES >> INSPECTION END
NO >> Go to EC-313, "
Diagnosis Procedure".
Diagnosis ProcedureINFOID:0000000001671101
1.CHECK FUEL INJECTOR POWER SUPPLY CIRCUIT
