COMPRESSION PRESSURE
On-Vehicle ServiceINFOID:0000000009460536
CHECKING COMPRESSION PRESSURE
1. Run the engine until it reaches normal operating temperature.
2. Turn the ignition switch to OFF.
3. Release fuel pressure and leave t he fuel pump electrically disconnected.
Refer to EC-687, "Work Procedure"
.
4. Remove all six spark plugs. Refer to EM-132, "Removal and Installation"
.
5. Install the compression tester with the adapter into the spark plug hole. • Use compression tester whose end (a) (rubber portion) is
smaller than 20 mm (0.79 in) in diameter. Otherwise, it may be
caught by cylinder head during removal.
6. Depress accelerator pedal fully to keep the electric throttle control actuator butterfly-valve wide open to
maximize air intake flow.
7. Crank the engine and record the highest gauge indication.
8. Repeat the measurement on each cylinder (steps 5 - 7). NOTE:
Always use a fully charged battery to obtain specified engine speed.
Unit: kPa (kg/cm2, psi)/rpm
9. If compression in one or more cylinders is low:
a. Pour a small amount of engine oil into cylinders through the spark plug holes.
b. Retest compression (steps 5 - 8).
• If adding oil helps raise compression pressure, then the piston rings may be worn or damaged. If so, replace piston rings after checking piston.
• If the pressure stays low, a valve may be sticking or is seating improperly. Inspect and repair the valve and/
or valve seat. Refer to EM-212, "Inspection After Disassembly"
. If the valve and/or valve seat is damaged
replace as necessary.
• If compression stays low in two or more cylinders that are next to each other:
- The cylinder head gasket may be leaking.
- Both cylinders may have valve component damage. Inspect and repair as necessary.

INTAKE MANIFOLD
6. Loosen the bolts in the order as shown, and remove the intake
manifold.
INSPECTION AFTER REMOVAL
Surface Distortion
• Using straightedge and feeler gauge, inspect the surface distortion of the intake manifold. Refer to EM-146, "Removal and Installa-
tion".
INSTALLATION
Installation is in the reverse order of removal. Fo llow the procedure below for specific tightening sequences
and procedures.
CAUTION:
Do not reuse intake manifold gaskets.
• Install intake manifold nuts and bolts in two steps in the numerical order as shown.
NOTE:
After installation, it is necessary to re-calibrate the electric throttle control actuator as follows:
1. Perform the "Throttle Valve Closed Position Learning" when harness connector of the electric throttle con-
trol actuator is disconnected. Refer to EC-682, "Work Procedure"
.
2. Perform the "Idle Air Volume Learning" when the electric throttle control actuator is replaced. Refer to EC-
683, "Work Procedure".
3. Install the quick connector. Refer to EM-163, "Removal and Installation"
.
INSPECTION AFTER INSTALLATION
Make sure there are no fuel leaks at the connections as follows:
1. Apply fuel pressure to fuel lines by turning ignition switch ON (with engine stopped). Then check for fuel leaks at connections.
2. Start the engine and rev it up and check for fuel leaks at connections. WARNING:
Do not touch engine immediately after stopping as engine is extremely hot.
NOTE:
Use mirrors for checking on connections out of the direct line of sight.

INSPECTION OF CAMSHAFT SPROCKET (INT) OIL GROOVE
WARNING:
• Check when engine is cold so as to pr event burns from any splashing engine oil.
CAUTION:
• Perform this inspection only when DTC P0011 is detected in self-diagnostic results of CONSULT and
it is directed according to inspection procedure of EC section. Refer to EC-716, "Diagnosis Proce-
dure".
1. Check engine oil level. Refer to MA-26, "ENGINE OIL : Inspection"
.
2. Perform the following procedure so as to prevent the engine from being unintentionally started while
checking.
a. Release fuel pressure. Refer to FL-5, "Inspection"
.
b. Disconnect ignition coil and injector harness connectors if practical.
3. Remove intake valve timing control solenoid valve.
4. Crank engine, and then make sure that engine oil comes out from intake valve timing control solenoid valve cover oil hole.
End cranking after checking.
WARNING:
Be careful not to touch rotating parts (drive belts, idler pul-
ley, and crankshaft pulley, etc.).
CAUTION:
• Engine oil may squirt from intake valve timing control solenoid valve installation hole during cranking. Use a
shop cloth to prevent engi ne oil from splashing on
worker, engine components and vehicle.
• Do not allow engine oil to get on rubber components such
as drive belts or engine mount insulators. I mmediately wipe off any splashed engine oil.
5. Clean oil groove between oil strainer and intake valve timing control solenoid valve if engine oil does not come out from intake valve timing control solenoid valve cover oil hole.
6. Remove components between intake valve timing c ontrol solenoid valve and camshaft sprocket (INT),
and then check each oil groove for clogging.
• Clean oil groove if necessary.
7. After inspection, installation of the remaining components is in the reverse order of removal.

Precaution for Supplemental Restraint Syst
em (SRS) "AIR BAG" and "SEAT BELT
PRE-TENSIONER"
INFOID:0000000009951692
The Supplemental Restraint System such as “A IR BAG” and “SEAT BELT PRE-TENSIONER”, used along
with a front seat belt, helps to reduce the risk or severi ty of injury to the driver and front passenger for certain
types of collision. Information necessary to service the system safely is included in the SR and SB section of
this Service Manual.
WARNING:
• To avoid rendering the SRS inopera tive, which could increase the risk of personal injury or death in
the event of a collision which would result in air bag inflation, all maintenance must be performed by
an authorized NISS AN/INFINITI dealer.
• Improper maintenance, including in correct removal and installation of the SRS, can lead to personal
injury caused by unintent ional activation of the system. For re moval of Spiral Cable and Air Bag
Module, see the SR section.
• Do not use electrical test equipmen t on any circuit related to the SRS unless instructed to in this
Service Manual. SRS wiring harn esses can be identified by yellow and/or orange harnesses or har-
ness connectors.
PRECAUTIONS WHEN USING POWER TOOLS (AIR OR ELECTRIC) AND HAMMERS
WARNING:
• When working near the Airbag Diagnosis Sensor Unit or other Airbag System sensors with the Igni-
tion ON or engine running, DO NOT use air or electri c power tools or strike near the sensor(s) with a
hammer. Heavy vibration could activate the sensor( s) and deploy the air bag(s), possibly causing
serious injury.
• When using air or electric power tools or hammers , always switch the Ignition OFF, disconnect the
battery and wait at least three minutes before performing any service.
