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.

On Board Diagnosis LogicEBS010TB
If the cooling fan or another component in the cooling system malfunctions, engine coolant temperature will
rise. When the engine coolant temperature reaches an abnormally high temperature condition, a malfunction
is indicated.
This self-diagnosis has the one trip detection logic.
CAUTION:
When a malfunction is indicated, be sure to replace the coolant. Refer to CO-9, "
Changing Engine
Coolant" . Also, replace the engine oil. Refer to LU-8, "Changing Engine Oil" .
1. Fill radiator with coolant up to specified level with a filling speed of 2 liters per minute. Be sure to
use coolant with the proper mixture ratio. Refer to MA-19, "
Engine Coolant Mixture Ratio" .
2. After refilling coolant, run engine to ensure that no water-flow noise is emitted.
Overall Function CheckEBS010TC
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 pres-
sure 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.

NOTE:
Prepare pans or saucers under the disconnected fuel line because the fuel may spill out. The fuel pres-
sure cannot be completely released because T30 models do not have fuel return system.
CAUTION:
The fuel hose connection method used when taking fuel pressure check must not be used for
other purposes.
Be careful not to scratch or put debris around connection area when servicing, so that the quick
connector maintains sealability with O-rings inside.
When installing fuel hose quick connector, refer to EM-17, "INTAKE MANIFOLD" .
1. Release fuel pressure to zero. Refer to EC-510, "
FUEL PRESSURE RELEASE" .
2. Prepare fuel hose and fuel hose clamp for fuel pressure check, and connect fuel pressure gauge.
Use suitable fuel hose for fuel pressure check (genuine NISSAN fuel hose without quick connector).
To avoid unnecessary force or tension to hose, use moderately long fuel hose for fuel pressure check.
Do not use the fuel hose for checking fuel pressure with damage or cracks on it.
Use Pressure Gauge to check fuel pressure.
3. Remove fuel hose. Refer to EM-17, "
INTAKE MANIFOLD" .
Do not twist or kink fuel hose because it is plastic hose.
Do not remove fuel hose from quick connector.
Keep the original fuel hose to be free from intrusion of dust or foreign substances with a suitable cover.
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.

DTC P0011 IVT CONTROLPFP:23796
DescriptionEBS010XU
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.
