DTC LogicINFOID:0000000005398434
DTC DETECTION LOGIC
The ECM monitors the switching frequency ratio of air fuel ratio (A/F)
sensor 1 and heated oxygen sensor 2.
A three way catalyst (manifold) with high oxygen storage capacity
will indicate a low switching frequency of heated oxygen sensor 2.
As oxygen storage capacity decreases, the heated oxygen sensor 2
switching frequency will increase.
When the frequency ratio of A/F sensor 1 and heated oxygen sensor
2 approaches a specified limit value, the three way catalyst (mani-
fold) malfunction is diagnosed.
DTC CONFIRMATION PROCEDURE
1.INSPECTION START
Do you have CONSULT-III?
Do you have CONSULT-III?
YES >> GO TO 2.
NO >> GO TO 7.
2.PRECONDITIONING
If DTC Confirmation Procedure has been previously conducted, always turn ignition switch OFF and wait at
least 10 seconds before conducting the next test.
TESTING CONDITION:
Do not hold engine speed for more than the specified minutes below.
>> GO TO 3.
3.PERFORM DTC CONFIRMATION PROCEDURE-I
With CONSULT-III
1. Turn ignition switch ON and select “DATA MONITOR” mode with CONSULT-III.
2. Start engine and warm it up to normal operating temperature.
3. Turn ignition switch OFF and wait at least 10 seconds.
4. Start engine and keep the engine speed between 3,500 and 4,000 rpm for at least 1 minute under no load.
5. Let engine idle for 1 minute.
6. Make sure that “COOLAN TEMP /S” indication is more than 70°C (158°F).
If not, warm up engine and go to next step w hen “COOLAN TEMP/S” indication reaches 70 °C (158° F).
7. Open engine hood.
8. Select “DTC & SRT CONFIRMATION” then “SRT WORK SUPPORT” mode with CONSULT-III.
9. Rev engine up to 2,000 to 3,000 rpm and hold it for 3 consecutive minutes then release the accelerator
pedal completely.
10. Check the indication of “CATALYST”.

2. Set the pressure pump and a hose.
3. Also set a vacuum gauge via 3-way connector and a hose.
4. Turn ignition switch ON.
5. Connect GST and select Service $08.
6. Using Service $08 control the EVAP canister vent control valve
(close).
7. Apply pressure and make sure the following conditions are sat-
isfied.
Pressure to be applied: 2.7 kPa (0.028 kg/cm
2, 0.39 psi)
Time to be waited after the pressure drawn in to the EVAP
system and the pressure to be dropped: 60 seconds and
the pressure should not be dropped more than 0.4 kPa
(0.004 kg/cm
2, 0.06 psi).
Is the inspection result normal?
YES >> GO TO 2.
NO >> Go to EC-331, "
Diagnosis Procedure".
2.RELEASE PRESSURE
1. Disconnect GST.
2. Start engine and warm it up to normal operating temperature.
3. Turn ignition switch OFF and wait at least 10 seconds.
4. Restart engine and let it idle for 90 seconds.
5. Keep engine speed at 2,000 rpm for 30 seconds.
6. Turn ignition switch OFF. NOTE:
For more information, refer to GST Instruction Manual.

Diagnosis ProcedureINFOID:0000000005398485
1.CHECK FUEL FILLER CAP DESIGN
1. Turn ignition switch OFF.
2. Check for genuine NISSAN fuel filler cap design.
Is the inspection result normal?
YES >> GO TO 2.
NO >> Replace with genuine NISSAN fuel filler cap.
2.CHECK FUEL FILLER CAP INSTALLATION
Check that the cap is tightened properly by rotating the cap clockwise.

EVAPORATIVE EMISSION SYSTEM
Check EVAP canister as follows:
1. Block port
(B).
2. Blow air into port (A) and confirm that it flows freely out of port
(C) .
3. Release blocked port (B) .
4. Apply vacuum pressure to port (B) and confirm that vacuum
pressure exists at the ports (A) and ( C).
5. Block port (A) and ( B).
6. Apply pressure to port (C) and check that there is no leakage.
FUEL TANK VACUUM RELIEF VALVE (BUILT INTO FUEL FILLER CAP)
1. Wipe clean valve housing.
2. Check valve opening pressure and vacuum.
3. If out of specification, replace fuel filler cap as an assembly.
CAUTION:
Use only a genuine fuel filler cap as a replacement. If an incor-
rect fuel filler cap is used, the MIL may come on.

8. Select “DTC & SRT CONFIRMATION” then “SRT WORK SUPPORT” mode with CONSULT-III.
9. Rev engine up to 2,000 to 3,000 rpm and hold it for 3 consecutive minutes then release the accelerator pedal completely.
If “INCMP” of “CATALYST” changed to “CMPLT”, go to step 12.
10. Wait 5 seconds at idle.
11. Rev engine up to 2,000 to 3,000 rpm and maintain it unt il “INCMP” of “CATALYST” changes to “CMPLT” (It
will take approximately 5 minutes).
If not “CMPLT”, stop engine and cool it down to less than 70 °C (158° F) and then retest from step 1.
12. Check 1st trip DTC. If 1st trip DTC is detected, go to EC-806, "
Diagnosis Procedure".
Overall Function CheckINFOID:0000000005532655

There is no fuel return path.
a. Remove quick connector cap (1) from quick connector connec- tion.
b. Disconnect fuel feed hose from hose clamp.
c. With the sleeve side of quick connector release facing quick connector, install quick connector release onto fuel tube.
d. Insert quick connector release into quick connector until sleeve contacts and goes no further. Hold quick connector release on
that position.
CAUTION:
Inserting quick connector re lease hard will not disconnect
quick connector. Hold qui ck connector release where it
contacts and goes no further.
e. Draw and pull out quick connector straight from fuel tube. CAUTION:
• Pull quick connector holding “A” position.
• Do not pull with lateral force applied. O-ring inside quickconnector may be damaged.
• Prepare container and cloth be forehand as fuel will leak out.
• Avoid fire and sparks.
• Keep parts away from heat source. Especially, be careful when welding is performed around
them.
• Do not expose parts to battery electrolyte or other acids.
• Do not bend or twist connection between quick co nnector and fuel feed hose during installation/
removal.
• To keep clean the connecting portion and to avoid dam- age and foreign materials, cover them completely with
plastic bags or something similar.
