DTC P2147, P2148 FUEL INJECTOR CIRCUIT

DTC P2147, P2148 FUEL INJECTOR CIRCUITPFP:16600
Component DescriptionEBS011F3
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 ModeEBS011F4
Specification data are reference values.
ECM Terminals and Reference ValueEBS011F5
Specification data are reference values and are measured between each terminal and ground.
CAUTION:
Do not use ECM ground terminals when measuring input/output voltage. Doing so may result in dam-
age to the ECM's transistor. Use a ground other than ECM terminals, such as the ground.
