DTC DETECTION LOGIC

This diagnosis detects a very large leak (fuel filler cap fell off etc.) in EVAP system between the fuel tank and

EVAP canister purge volume control solenoid valve.

CAUTION:

• Use only a genuine NISSAN fuel filler cap as a replacement. If an incorrect fuel filler cap is used, the

MIL may come on.

• If the fuel filler cap is not tightened properly, the MIL may come on.

• Use only a genuine NISSAN rubber tube as a replacement.

Never remove fuel filler cap during the DTC CONFIRMATION PROCEDURE.

If DTC Confirmation Procedure has been previously conducted, always turn ignition switch OFF and wait at

least 10 seconds before conducting the next test.

NOTE:

Make sure that EVAP hoses are connected to EVAP canister purge volume control solenoid valve

properly.

TESTING CONDITION:

• Perform “DTC WORK SUPPORT” when the fuel level is between 1/4 and 3/4 full, and vehicle is placed

on flat level surface.

• Open engine hood before conducting the following procedures.
Do you have CONSULT-III?

YES

>> GO TO 2.

NO

>> GO TO 4.

2.

PERFORM DTC CONFIRMATION PROCEDURE

With CONSULT-III

1. Tighten fuel filler cap securely until ratcheting sound is heard.

2. Turn ignition switch ON.

3. Turn ignition switch OFF and wait at least 10 seconds.

4. Turn ignition switch ON and select “DATA MONITOR” mode with CONSULT-III.

5. Make sure that the following conditions are met.

COOLAN TEMP/S: 0 - 70

°C (32 - 158°F)

INT/A TEMP SE: 0 - 60

°C (32 - 140°F)

6. Select “EVAP SML LEAK P0442/P1442” of “EVAPORATIVE SYSTEM” in “DTC WORK SUPPORT” mode

with CONSULT-III.

Follow the instruction displayed.

NOTE:
