DTC P0456 EVAP CONTROL SYSTEM
Revision: 2006 January2006 M35/M45
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.
DTC Confirmation ProcedureNBS005IM
NOTE:
If DTC P0456 is displayed with P0442, first perform trouble diagnosis for DTC P0456.
After repair, make sure that the hoses and clips are installed properly.
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:
Open engine hood before conducting following procedure.
If any of following conditions are met just before the DTC confirmation procedure, leave the vehi-
cle for more than 1 hour.
–Fuel filler cap is removed.
–Fuel is refilled or drained.
–EVAP component parts is/are removed.
Before performing the following procedure, confirm that battery voltage is more than 11V at idle.
WITH CONSULT-II
1. Turn ignition switch ON and select “DATA MONITOR” mode with CONSULT-II.
2. Make sure the following conditions are met.
FUEL LEVEL SE: 0.25 - 1.4V
COOLAN TEMP/S: 0 - 32
C (32 - 90F)
FUEL T/TMP SE: 0 - 35
C (32 - 95F)
INT A/TEMP SE: More than 0
C (32F)
If NG, turn ignition switch OFF and leave the vehicle in a cool place (soak the vehicle) or refilling/draining
fuel until the output voltage condition of the “FUEL LEVEL SE” meets within the range above and leave
the vehicle for more than 1 hour. Then start from step 1).
3. Turn ignition switch OFF and wait at least 10 seconds.
4. Turn ignition switch ON.
5. Select “EVAP V/S LEAK P0456/P1456” of “EVAPORATIVE SYSTEM” in “DTC WORK SUPPORT” mode
with CONSULT-II.
Follow the instruction displayed.
6. Make sure that “OK” is displayed.
If “NG” is displayed, refer to EC-1188, "
Diagnostic Procedure" .
NOTE:
If the engine speed cannot be maintained within the range displayed on CONSULT-II screen, go
to EC-788, "
Basic Inspection" .
Make sure that EVAP hoses are connected to EVAP canister purge volume control solenoid
valve properly.

Checking Fuel LinesNBS005R8
Inspect fuel lines, fuel filler cap and fuel tank for improper attach-
ment, leaks, cracks, damage, loose connections, chafing or deterio-
ration.
If necessary, repair or replace damaged parts.
General PrecautionsNBS005R9
WAR NING :
When replacing fuel line parts, be sure to observe the following.
Put a “CAUTION: FLAMMABLE” sign in the workshop.
Be sure to work in a well ventilated area and furnish workshop with a CO2 fire extinguisher.
Do not smoke while servicing fuel system. Keep open flames and sparks away from the work area.
CAUTION:
Use gasoline required by the regulations for octane number. Refer to GI-6, "Precautions for Fuel
(Unleaded Premium Gasoline Required)" .
Before removing fuel line parts, perform out the following procedures:
–Put drained fuel in an explosion-proof container and put the lid on securely. Keep the container in
safe area.
–Release fuel pressure from the fuel lines. Refer to EC-98, "FUEL PRESSURE RELEASE" (VQ35DE)
or EC-809, "
FUEL PRESSURE RELEASE" (VK45DE).
–Disconnect the battery cable from the negative terminal.
Always replace O-ring and clamps with new ones.
Do not kink or twist tubes when they are being installed.
Do not tighten hose clamps excessively to avoid damaging hoses.
After connecting fuel tube quick connectors, make sure
quick connectors are secure.
Ensure that connector and resin tube do not contact any
adjacent parts.
After installing tubes, make sure there is no fuel leakage at
connections in the following steps.
–Apply fuel pressure to fuel lines with turning ignition switch
“ON” (with engine stopped). Then check for fuel leaks at
connections.
–Start engine and rev it up and check for fuel leaks at con-
nections.
Use only a genuine NISSAN fuel filler cap as a replacement.
If an incorrect fuel filler cap is used, the “MIL” may come
on.
For servicing “Evaporative Emission System” parts, refer to
EC-39, "
EVAPORATIVE EMISSION SYSTEM" (VQ35DE) or
EC-749, "
EVAPORATIVE EMISSION SYSTEM" (VK45DE).
For servicing“On Board Refueling Vapor Recovery (ORVR)”
parts, refer to EC-46, "
ON BOARD REFUELING VAPOR
RECOVERY (ORVR)" (VQ35DE) or EC-756, "ON BOARD
REFUELING VAPOR RECOVERY (ORVR)" (VK45DE).

Nickel Metal Hydride Battery Replacement NAS0007U
CONSULT-II contains a nickel metal hydride battery. When replacing the battery obey the following:
WAR NING :
Replace the nickel metal hydride battery with Genuine CONSULT-II battery only. Use of another bat-
tery may present a risk of fire or explosion. The battery may present a fire or chemical burn hazard if
mistreated. Do not recharge, disassemble or dispose of in fire.
Keep the battery out of reach of children and discard used battery conforming to the local regulations.
Checking Equipment NAS0007V
When ordering the following equipment, contact your NISSAN/INFINITI distributor.
NOTE:
The CONSULT-II must be used in conjunction with a program card.
CONSULT-II does not require loading (Initialization) procedure.
Be sure the CONSULT-II is turned off before installing or removing a program card.
CAUTION:
If CONSULT-II is used with no connection of CONSULT-II CONVERTER, malfunctions might be
detected in self-diagnosis depending on control unit which carry out CAN communication.
If CONSULT-II CONVERTER is not connected with CONSULT-II, vehicle occur the “FAIL SAFE
MODE” which is “LIGHT UP the HEAD LIGHT” and/or “COOLING FAN ROTAT I N G ” w h e n C O N -
SULT-II is started.
Previous CONSULT-II “I” and “Y” DLC-I and DLC-II cables should NOT be used anymore because
their DDL connector pins can be damaged during cable swapping.
CONSULT-II Start ProcedureNAS0007W
NOTE:
Turning ignition switch off when performing CAN diagnosis could cause CAN memory to be erased.
1. Connect CONSULT-II and CONSULT-II CONVERTER to the
data link connector.
