DTC P0201 - P0204 FUEL INJECTORPFP:16600
Component DescriptionEBS0119P
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 cylinder. The
amount of fuel injected depends upon the injection pulse duration.
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 ModeEBS0119Q
Specification data are reference values.
ECM Terminals and Reference ValueEBS0119R
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.
