DTC P0201 - P0204 FUEL INJECTOR
DTC P0201 - P0204 FUEL INJECTOR
PFP:16600
Component Description
EBS013B7
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 Mode
EBS013B8
Specification data are reference values.
ECM Terminals and Reference Value
EBS013B9
Specification data are reference values and are measured between each terminal and ground.
Pulse signal is measured by CONSULT-II.
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.

2.
Select “DATA MONITOR” mode with CONSULT-II.
3.
Start engine and let it idle for at least 5 seconds.
4.
If 1st trip DTC is detected, go to
.
WITH GST
Follow the procedure “WITH CONSULT-II” above.
