DTC P1268 - P1271 FUEL INJECTORPFP:16600
Component DescriptionEBS011DG
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 needle valve back and
allows fuel to flow through the fuel injector into the intake cylinder.
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.
CONSULT-II Reference Value in Data Monitor ModeEBS011DH
Specification data are reference values.
On Board Diagnosis LogicEBS011DJ
This self-diagnosis has the one trip detection logic.
The MI will not light up for these self-diagnoses.
