FUEL PRESSURE RELEASE
With CONSULT-II
1. Turn ignition switch ON.
2. Perform “FUEL PRESSURE RELEASE” in “WORK SUPPORT”
mode with CONSULT-II.
3. Start engine.
4. After engine stalls, crank it two or three times to release all fuel
pressure.
5. Turn ignition switch OFF.
Without CONSULT-II
1. Remove fuel pump fuse (1) located in IPDM E/R (2).
: Vehicle front
2. Start engine.
3. After engine stalls, crank it two or three times to release all fuel
pressure.
4. Turn ignition switch OFF.
5. Reinstall fuel pump fuse after servicing fuel system.
FUEL PRESSURE CHECK
CAUTION:
Before disconnecting fuel line, release fuel pressure from fuel line to eliminate danger.
NOTE:
Prepare pans or saucers under the disconnected fuel line because the fuel may spill out. The fuel
pressure cannot be completely released because C11 models do not have fuel return system.
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.
Do not perform fuel pressure check with electrical systems operating (i.e. lights, rear defogger, A/
C, etc.) Fuel pressure gauge may indicate false readings due to varying engine load and changes
in manifold vacuum.
1. Release fuel pressure to zero. Refer to EC-81, "
FUEL PRESSURE RELEASE" .
2. Prepare fuel hose for fuel pressure check B and fuel tube
adapter (KV10118400) D, then connect fuel pressure gauge A.
: To quick connector
: To fuel tube (engine side)
C: Clamp
Use suitable fuel hose for fuel pressure check (genuine NIS-
SAN fuel hose without quick connector).
To avoid unnecessary force or tension to hose, use moder-
ately long fuel hose for fuel pressure check.
Do not use the fuel hose for checking fuel pressure with dam-
age or cracks on it.
Use Pressure Gauge to check fuel pressure.
3. Remove fuel hose. Refer to EM-18, "
INTAKE MANIFOLD" .

EC-82Revision: June 2006
BASIC SERVICE PROCEDURE
2007 Versa
Do not twist or kink fuel hose because it is plastic hose.
4. Connect fuel hose for fuel pressure check (1) to fuel tube
(engine side) with clamp (2) as shown in the figure.
No.2 spool (5)
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
(3) and No.1 spool (4).
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.
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. Connect fuel tube adapter to quick connector.
A: Fuel pressure gauge
B: Fuel hose for fuel pressure check
6. 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.
7. Turn ignition switch ON and check for fuel leakage.
8. Start engine and check for fuel leakage.
9. 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.
10. If result is unsatisfactory, go to next step.
11. 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.
12. 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.
13. Before disconnecting Fuel Pressure Gauge and Fuel Pressure Adapter J-44321-6, release fuel pressure
to zero. Refer to EC-81, "
FUEL PRESSURE RELEASE" . Tightening torque: 1 - 1.5 N·m (0.1 - 0.15 kg-m, 9 - 13 in-lb)
At idling: Approximately 350 kPa (3.5 bar, 3.57 kg/cm
2 , 51 psi)

10. DETECT MALFUNCTIONING PART BY DIAGNOSTIC PROCEDURE
Inspect according to Diagnostic Procedure of the system.
NOTE:
The Diagnostic Procedure in EC section described based on open circuit inspection. A short circuit inspection
is also required for the circuit check in the Diagnostic Procedure. For details, refer to Circuit Inspection in GI-
27, "How to Perform Efficient Diagnosis for an Electrical Incident" .
Is malfunctioning part detected?
Yes >> GO TO 11.
No >> Monitor input data from related sensors or check voltage of related ECM terminals using CON-
SULT-II. Refer to EC-105, "
ECM Terminals and Reference Value" , EC-128, "CONSULT-II Refer-
ence Value in Data Monitor" .
11 . REPAIR OR REPLACE THE MALFUNCTIONING PART
1. Repair or replace the malfunctioning part.
2. Reconnect parts or connectors disconnected during Diagnostic Procedure again after repair and replace-
ment.
3. Check DTC. If DTC is displayed, erase it, refer to EC-60, "
HOW TO ERASE EMISSION-RELATED DIAG-
NOSTIC INFORMATION" .
>> GO TO 12.
12. FINAL CHECK
When DTC was detected in step 2, perform DTC Confirmation Procedure or Overall Function Check again,
and then make sure that the malfunction have been repaired securely.
When symptom was described from the customer, refer to confirmed symptom in step 3 or 4, and make sure
that the symptom is not detected.
OK or NG
NG (DTC*1 is detected)>>GO TO 10.
NG (Symptom remains)>>GO TO 6.
OK >> 1. Before returning the vehicle to the customer, make sure to erase unnecessary DTC*
1 in ECM
and TCM (Transmission Control Module). (Refer to EC-60, "
HOW TO ERASE EMISSION-
RELATED DIAGNOSTIC INFORMATION" and AT-39, "OBD-II Diagnostic Trouble Code
(DTC)" , CVT-30, "OBD-II Diagnostic Trouble Code (DTC)" .)
2. If the completion of SRT is needed, drive vehicle under the specific driving pattern. Refer to EC-
57, "Driving Pattern" .
3.INSPECTION END
*1: Include 1st trip DTC.
*2: Include 1st trip freeze frame data.
DIAGNOSTIC WORKSHEET
Description
There are many operating conditions that lead to the malfunction of
engine components. A good grasp of such conditions can make trou-
bleshooting faster and more accurate.
In general, each customer feels differently about a incident. It is
important to fully understand the symptoms or conditions for a cus-
tomer complaint.
Utilize a diagnostic worksheet like the one on the next page in order
to organize all the information for troubleshooting.
Some conditions may cause the MIL to come on steady or blink and
DTC to be detected. Examples:
Vehicle ran out of fuel, which caused the engine to misfire.
Fuel filler cap was left off or incorrectly screwed on, allowing fuel
to evaporate into the atmosphere.
