DTC P0201 - P0204 FUEL INJECTOR

DTC P0201 - P0204 FUEL INJECTORPFP:16600
Component DescriptionEBS011ZW
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 ModeEBS011ZX
Specification data are reference values.
ECM Terminals and Reference ValueEBS011ZY
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.

Overall Function CheckEBS01209
Use this procedure to check the overall function of the cooling fan. During this check, a DTC might not be con-
firmed.
WARNING:

Never remove the radiator cap when the engine is hot. Serious burns could be caused by high
pressure fluid escaping from the radiator.

Wrap a thick cloth around cap. Carefully remove the cap by turning it a quarter turn to allow built-
up pressure to escape. Then turn the cap all the way off.
WITH CONSULT-II
1. Check the coolant level in the reservoir tank and radiator.
Allow engine to cool before checking coolant level.
If the coolant level in the reservoir tank and/or radiator is below
the proper range, skip the following steps and go to EC-1323,
"Diagnostic Procedure" .
2. Confirm whether customer filled the coolant or not. If customer
filled the coolant, skip the following steps and go to EC-1323,
"Diagnostic Procedure" .
3. Turn ignition switch ON.
4. Perform “COOLING FAN” in “ACTIVE TEST” mode with CON-
SULT-II.
5. If the results are NG, go to EC-1323, "
