FUEL PRESSURE
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.Tightening torque: 1 - 1.5 N·m (0.1 - 0.15 kg-m, 9 - 13 in-lb)

Check that air flows freely through port (C).
3. Visually inspect the fuel check valve for cracks, damage, loose connections chafing and deterioration.
4. Check fuel check valve as follows:
a. Blow air through connector on the fuel tank side. A considerable
resistance should be felt and a portion of air flow should be
directed toward the EVAP canister side.
b. Blow air through connector on EVAP canister side. Air flow
should be smoothly directed toward fuel tank side.
c. If fuel check valve is suspected or not properly functioning in
step 1 and 2 above, replace it.
5. Inspect fuel tank filler cap vacuum relief valve for clogging, stick-
ing, etc.
a. Wipe clean valve housing.

DIAGNOSIS AND REPAIR WORKFLOW
1.GET INFORMATION FOR SYMPTOM
Get the detailed information from the customer about the symptom (the condition and the environment when
the incident/malfunction occurred) using the “Diagnostic Work Sheet”. (Refer to EC-687, "
Diagnostic Work
Sheet".)
>> GO TO 2.
2.CHECK DTC
1. Check DTC.
2. Perform the following procedure if DTC is displayed.
- Record DTC and freeze frame data. (Print them out with CONSULT-III or GST.)
- Erase DTC. (Refer to EC-760, "
Diagnosis Description".)
- Study the relationship between the cause detected by DTC and the symptom described by the customer.
(Symptom Table is useful. Refer to EC-1024, "
Symptom Table".)
3. Check related service bulletins for information.
Is any symptom described and is any DTC detected?
Symptom is described, DTC is detected>>GO TO 3.
Symptom is described, DTC is not detected>>GO TO 4.
Symptom is not described, DTC is detected>>GO TO 5.
3.CONFIRM THE SYMPTOM
Try to confirm the symptom described by the customer (except MI ON).
Also study the normal operation and fail safe related to the symptom. Refer to EC-1028, "
Description" and EC-
1017, "FailSafe".
Diagnosis Work Sheet is useful to verify the incident.
Verify relation between the symptom and the condition when the symptom is detected.
>> GO TO 5.
4.CONFIRM THE SYMPTOM
Try to confirm the symptom described by the customer.
Also study the normal operation and fail safe related to the symptom. Refer to EC-1028, "
Description" and EC-
1017, "FailSafe".
Diagnosis Work Sheet is useful to verify the incident.
Verify relation between the symptom and the condition when the symptom is detected.
>> GO TO 6.
5.PERFORM DTC CONFIRMATION PROCEDURE
Perform DTC CONFIRMATION PROCEDURE for the displayed DTC, and then make sure that DTC is
detected again.
If two or more DTCs are detected, refer to EC-1019, "
DTCInspectionPriorityChart" and determine trouble
diagnosis order.
NOTE:
 Freeze frame data is useful if the DTC is not detected.
 Perform Component Function Check if DTC CONFIRMATION PROCEDURE is not included on Service
Manual. This simplified check procedure is an effective alternative though DTC cannot be detected during
this check.
If the result of Component Function Check is NG, it is the same as the detection of DTC by DTC CONFIR-
MATION PROCEDURE.
Is DTC detected?
YES >> GO TO 10.
NO >> Check according to EC-1020, "
DTCIndex".
6.PERFORM BASIC INSPECTION
Perform EC-689, "
BASIC INSPECTION : Special Repair Requirement".
Do you have CONSULT-III?

step 4, and determine the trouble diagnosis order based on possible causes and symptom.
>> GO TO 10.
10.DETECT MALFUNCTIONING PART BY DIAGNOSIS PROCEDURE
Inspect according to Diagnosis Procedure of the system.
NOTE:
The Diagnosis Procedure in EC section described based on open circuit inspection. A short circuit inspection
is also required for the circuit check in the Diagnosis Procedure. For details, refer to Circuit Inspection in GI-
58, "Circuit Inspection".
Is malfunctioning part detected?
YES >> GO TO 11.
NO >> Monitor input data from related sensors or check the voltage of related ECM terminals using CON-
SULT-III. Refer to EC-990, "
Reference Value".
11 .REPAIR OR REPLACE THE MALFUNCTIONING PART
1. Repair or replace the malfunctioning part.
2. Reconnect parts or connectors disconnected during Diagnosis Procedure again after repair and replace-
ment.
3. Check DTC. If DTC is displayed, erase it. Refer to EC-760, "
Diagnosis Description".
>> GO TO 12.
12.FINAL CHECK
When DTC was detected in step 2, perform DTC CONFIRMATION PROCEDURE or Component 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.
Is DTC detected and does symptom remain?
YES-1 >> DTC is detected: GO TO 10.
YES-2 >> Symptom remains: GO TO 6.
NO >> Before returning the vehicle to the customer, make sure to erase unnecessary DTC in ECM and
TCM (Transmission Control Module). (Refer to EC-760, "
Diagnosis Description".) If the comple-
tion of SRT is needed, drive vehicle under the specific DRIVING PATTERN in EC-1021,
"HowtoSetSRTCode".

DESCRIPTION

EC-688
< BASIC INSPECTION >[MR18DE]
DIAGNOSIS AND REPAIR WORKFLOW
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 MI to come on steady or blink and
DTC to be detected. Examples:
Vehicle ran out of fuel, which caused the engine to misfire.
