Install transaxle assembly to engine assembly with a hoist.

When installing fluid cooler tube to transaxle assembly, assem-
ble the part with the tube aligned with the rib.

When installing transaxle to the engine, attach the fixing bolts in
accordance with the following standard.

Align the positions of tightening nuts for drive plate with those of
the torque converter, and temporarily tighten the nuts. Then,
tighten the nuts with the specified torque.
CAUTION:

When turning crankshaft, turn it clockwise as viewed
from the front of the engine.

When tightening the tightening nuts for the torque con-
verter after fixing the crankshaft pulley bolts, be sure to
confirm the tightening torque of the crankshaft pulley
mounting bolts. Refer to EM-181, "
INSTALLATION" .

After converter is installed to drive plate, rotate crankshaft several turns and check to be sure
that transaxle rotates freely without binding.

Install crankshaft position sensor (POS). Refer to EM-145, "Removal and Installation" .

After completing installation, check for fluid leakage, fluid level, and the positions of CVT. Refer to CVT-13,
"Checking CVT Fluid" , CVT-178, "Adjustment of CVT Position" , CVT-179, "Checking of CVT Position" .

When replacing the CVT assembly, erase EEP ROM in TCM. Refer to CVT-9, "Precautions for TCM and
CVT Assembly Replacement" .

PRECAUTIONS


After performing each TROUBLE DIAGNOSIS, perform DTC
Confirmation Procedure or Overall Function Check.
The DTC should not be displayed in the DTC Confirmation
Procedure if the repair is completed. The Overall Function
Check should be a good result if the repair is completed.

When measuring ECM signals with a circuit tester, never
allow the two tester probes to contact.
Accidental contact of probes will cause a short circuit and
damage the ECM power transistor.

Do not use ECM ground terminals when measuring input/
output voltage. Doing so may result in damage to the ECM's
transistor. Use a ground other than ECM terminals, such as
the ground.

Do not operate fuel pump when there is no fuel in lines.

Tighten fuel hose clamps to the specified torque.

4. Install the fuel pressure gauge as shown in the figure.

Wipe off oil or dirt from hose insertion part using cloth moist-
ened with gasoline.

Apply proper amount of gasoline between top of the fuel tube
and No.1 spool.

Insert fuel hose for fuel pressure check until it touches the
No.1 spool on fuel tube.

Use NISSAN genuine hose clamp (part number: 16439
N4710 or 16439 40U00).

When reconnecting fuel line, always use new clamps.

When reconnecting fuel hose, check the original fuel hose for
damage and abnormality.

Use a torque driver to tighten clamps.

Install hose clamp to the position within 1 - 2 mm (0.04 - 0.08
in).

Make sure that clamp screw does not contact adjacent parts.
5. After connecting fuel hose for fuel pressure check, pull the hose
with a force of approximately 98 N (10 kg, 22 lb) to confirm fuel
tube does not come off.
6. Turn ignition switch ON, and check for fuel leakage.
7. Start engine and check for fuel leakage.
8. Read the indication of fuel pressure gauge.

Do not perform fuel pressure check with system operating. Fuel pressure gauge may indicate false
readings.

During fuel pressure check, confirm for fuel leakage from fuel connection every 3 minutes.
9. If result is unsatisfactory, go to next step.
10. Check the following.

Fuel hoses and fuel tubes for clogging

Fuel filter for clogging

Fuel pump

Fuel pressure regulator for clogging
If OK, replace fuel pressure regulator.
If NG, repair or replace.Tightening

DescriptionBBS005CP
SYSTEM DESCRIPTION
*: This signal is sent to the ECM through CAN communication line.
This mechanism hydraulically controls cam phases continuously with the fixed operating angle of the intake
valve.
The ECM receives signals such as crankshaft position, camshaft position, engine speed, and engine coolant
temperature. Then, the ECM sends ON/OFF pulse duty signals to the intake valve timing control solenoid
valve depending on driving status. This makes it possible to control the shut/open timing of the intake valve to
increase engine torque in low/mid speed range and output in high-speed range.
COMPONENT DISCRIPTION
Intake valve timing control solenoid valve is activated by ON/OFF
pulse duty (ratio) signals from the ECM.
The intake valve timing control solenoid valve changes the oil
amount and direction of flow through intake valve timing control unit
or stops oil flow.
The longer pulse width advances valve angle.
The shorter pulse width retards valve angle.
When ON and OFF pulse widths become equal, the solenoid valve
stops oil pressure flow to fix the intake valve angle at the control
position.

PRECAUTIONS


Do not operate fuel pump when there is no fuel in lines.

Tighten fuel hose clamps to the specified torque.

Do not depress accelerator pedal when starting.

Immediately after starting, do not rev up engine unneces-
sarily.

Do not rev up engine just prior to shutdown.

When installing C.B. ham radio or a mobile phone, be sure
to observe the following as it may adversely affect elec-
tronic control systems depending on installation location.
–Keep the antenna as far as possible from the electronic
control units.
–Keep the antenna feeder line more than 20 cm (8 in) away
from the harness of electronic controls.
Do not let them run parallel for a long distance.
–Adjust the antenna and feeder line so that the standing-
wave radio can be kept smaller.
–Be sure to ground the radio to vehicle body.
