DTC P2146, P2149 FUEL INJECTOR POWER SUPPLYPFP:16600
Component DescriptionEBS0124X
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 ModeEBS0124Y
Specification data are reference values.
ECM Terminals and Reference ValueEBS0124Z
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.

DTC P2147, P2148 FUEL INJECTOR CIRCUITPFP:16600
Component DescriptionEBS01254
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.

a. Using a screwdriver, separate the snap fit portion of bracket in
numerical order as shown in the figure.
CAUTION:
Put cloth or similar one on the edge of screwdriver not to
damage the inserted portion.
b. Pull out fuel pump, and disconnect harness connector.
2. Separate fuel filter and fuel level sensor unit as follows:
a. Fit a used O-ring into space between fuel level sensor unit and
fuel filter to release tabs.
NOTE:
For reference when reassembling, put a mating mark on outer
edges of fuel level sensor unit and fuel filter with some means
which cannot be erased by fuel.
b. Insert screwdriver to the gap between fuel filter and fuel level
sensor unit to separate them.
CAUTION:
Put cloth or similar one on the edge of screwdriver not to
damage the inserted portion.
3. Remove pressure regulator from fuel filter as follows:
a. Open and remove the clip.
b. Pull pressure regulator straight out during removal.
CAUTION:

Avoid impacts such as falling during removal.

Do not disassemble or adjust.
ASSEMBLY
Note the following, and assemble in the reverse order of disassembly.

Install fuel filter and fuel pump with the tabs aligned. Make sure a click sound of secure engagement is
heard.

Securely connect harness connector of fuel pump.

Install pressure regulator O-ring.
CAUTION:

When replacing, always use new O-ring.

Handle it with bare hands. (Do not use gloves.)

Visually check the O-ring, mounting parts and mating parts for foreign materials and flaws.

Before installing, apply new engine oil.

To avid damage, do not apply an excessive force (pulling or starching).
