FUEL INJECTORPFP:16600
Component DescriptionNBS005PV
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 ball valve back and
allows fuel to flow through the fuel injector into the intake manifold.
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.

DescriptionNBS005PK
SYSTEM DESCRIPTION
*: The ECM determines the start signal status by the signals of engine speed and battery voltage.
When the engine is running at low or medium speed, the power valve is fully closed. Under this condition, the
effective suction port length is equivalent to the total length of the intake manifold collector's suction port
including the intake valve. This long suction port provides increased air intake which results in improved suc-
tion efficiency and higher torque generation.
The surge tank and one-way valve are provided. When engine is running at high speed, the ECM sends the
signal to the VIAS control solenoid valve. This signal introduces the intake manifold vacuum into the power
valve actuator and therefore opens the power valve to two suction passages together in the collector.
Under this condition, the effective port length is equivalent to the length of the suction port provided indepen-
dently for each cylinder. This shortened port length results in enhanced engine output with reduced suction
resistance under high speeds.
The power valve is always open regardless of the engine speed when gear position is in N or P.

14. Screw a drive shaft puller (suitable tool) into joint sub-assembly
screw part to a length of 30 mm (1.18 in) or more. Support drive
shaft with one hand and pull out joint sub-assembly with a slid-
ing hammer (suitable tool) from shaft.
CAUTION:

Align a sliding hammer and drive shaft and remove them
by pulling firmly and uniformly.

If joint sub-assembly cannot be pulled out, try after
removing drive shaft from vehicle.
15. Remove the circular clip from shaft.
16. Remove boot from shaft.
17. Clean the old grease on joint sub-assembly with paper towels.
18. Apply the specified amount of grease (NISSAN genuine grease
or equivalent) inside joint sub-assembly serration hole until
grease begins to ooze from ball groove and serration hole. After
applying grease, use a shop cloth to wipe off old grease that has
oozed out.
19. Wrap serration on shaft with tape to protect the boot from dam-
age. Install new boot and boot bands to shaft.
20. Remove the tape wrapped around the serration on shaft.
21. Position circular clip on groove at the shaft edge. Align both
counter axles of the shaft edge and joint sub-assembly. Then,
assemble shaft with circular clip onto joint sub-assembly.
NOTE:
Drive joint inserter (suitable tool) is recommended when install-
ing circular clip.

22. Install joint sub-assembly to shaft using plastic hammer.
CAUTION:
Confirm that joint sub-assembly is correctly engaged while
rotating drive shaft.
23. Apply the balance of the specified amount of grease (NISSAN
genuine grease or equivalent) into the boot inside from large
diameter side of boot.
24. Install the boot securely into grooves (indicated by *marks)
shown in the figure.
CAUTION:
If grease adheres to the boot mounting surface (with *mark)
on the shaft and joint sub-assembly, boot may come off.
Remove all grease from the surface.
25. To prevent from the deformation of the boot, adjust the boot
installation length to the specified value shown below (L) by
inserting the flat-bladed screwdriver into inside of the boot from
the large diameter side of the boot and discharging the inside
air.
CAUTION:

If the boot mounting length is outside the standard, it may cause breakage in the boot.

Be careful not to touch the inside of the boot with a tip of a flat-bladed screwdriver.
26. Secure the large and small ends of the boot with new boot
bands using the boot band crimping tool [SST: KV40107300
( – )] as shown in the figure.
NOTE:
Secure boot band so that dimension “M” meets the specification
as shown.
27. Secure joint sub-assembly and shaft, and then make sure that
they are in the correct position when rotating boot. Install them
with new boot band when boot installation positions become
incorrect.
28. Insert drive shaft to wheel hub and bearing assembly, and then
temporarily tighten hub lock nut.
29. Install transverse link to steering knuckle. Refer to FAX-5,
"COMPONENT" .
30. Install steering outer socket to steering knuckle. Refer to FA X - 5 , "
COMPONENT" .
31. Install disc rotor. Refer to FAX-5, "
Removal and Installation" .
32. Install torque member fixing bolts to steering knuckle. Refer to BR-22, "
FRONT DISC BRAKE" .
33. Install brake hose bracket to steering knuckle. Refer to BR-11, "
BRAKE TUBE AND HOSE" . Grease amount : 77 – 97 g (2.71 – 3.42 oz)
