P0456 EVAP CONTROL SYSTEM
DTC LogicINFOID:0000000005929998
DTC DETECTION LOGIC
This diagnosis detects very small leaks in the EVAP line between fuel tank and EVAP canister purge volume
control solenoid valve, using the intake manifold vacuum in the same way as conventional EVAP small leak
diagnosis.
If ECM judges a leak which corresponds to a very
small leak, the very small leak P0456 will be detected.
If ECM judges a leak equivalent to a small leak, EVAP small leak P0442 will be detected.
If ECM judges there are no leaks, the diagnosis will be OK.
CAUTION:
• Use only a genuine NISSAN fuel filler cap as a replacemen t. If an incorrect fuel filler cap is used, the
MIL may come on.
• If the fuel filler cap is not tigh tened properly, the MIL may come on.

Do you have CONSULT-III?
YES >> GO TO 2.
NO >> GO TO 4.
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.
NOTE:
• If DTC P0456 is displayed with P0442, firs t perform trouble diagnosis for DTC P0456.
• After repair, make sure that the hoses and clips are installed properly.
• Make sure that EVAP hoses are connected to EVAP canister purge volume control solenoid valve
properly.
TESTING CONDITION:
• Open engine hood before conducting following procedure.
• If any of following conditions are met just be fore the DTC CONFIRMATION PROCEDURE, leave the
vehicle 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 th at battery voltage is more than 11 V at idle.
>> GO TO 3.
3.PERFORM DTC CONFIRMATION PROCEDURE
With CONSULT-III
1. Turn ignition switch ON and select “DATA MONITOR” mode with CONSULT-III.
2. Make sure the following conditions are met.
FUEL LEVEL SE: 0.25 - 1.4 V
COOLAN TEMP/S: 0 - 32 °C (32 - 90° F)
FUEL T/TMP SE: 0 - 35° C (32 - 95°F)
INT A/TEMP SE: More than 0° C (32°F)
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 “EVP V/S LEAK P0456/P1456” of “EVAPORATIVE SYSTEM” in “DTC WORK SUPPORT” mode with CONSULT-III.
Follow the instruction displayed.
NOTE:
If the engine speed canno t be maintained within the range displayed on CONSULT-III screen, go to
EC-20, "
BASIC INSPECTION : Special Repair Requirement".
Which is displayed on CONSULT-III?
OK >> INSPECTION END
NG >> Go to EC-341, "
Diagnosis Procedure".
4.PERFORM COMPONENT FUNCTION CHECK
Perform component function check. Refer to EC-341, "
Component Function Check".
NOTE:
Use component function check to check the overall function of the EVAP very small leak function. During this
check, a 1st trip DTC might not be confirmed.
Is the inspection result normal?
YES >> INSPECTION END

P0460 FUEL LEVEL SENSOR
P0460 FUEL LEVEL SENSOR
DescriptionINFOID:0000000005930003
The fuel level sensor is mounted in the fuel level sensor unit.
The sensor detects a fuel level in the fuel tank and transmits a signal to the combination meter. The combina-
tion meter sends the fuel level sensor signal
to the ECM via the CAN communication line.
It consists of two parts, one is mechanical float and the ot her is variable resistor. Fuel level sensor output volt-
age changes depending on the movement of the fuel mechanical float.
DTC LogicINFOID:0000000005930004
DTC DETECTION LOGIC
NOTE:
• If DTC P0460 is displayed with DTC UXXXX, first perform the trouble diagnosis for DTC UXXXX.
• If DTC P0460 is displayed with DTC P0607, first perform the trouble diagno sis for DTC P0607. Refer
to EC-361, "
DTC Logic".
When the vehicle is parked, naturally the fuel level in the fuel tank is stable. It means that output signal of the
fuel level sensor does not change. If ECM senses sloshi ng signal from the sensor, fuel level sensor malfunc-
tion is detected.
DTC CONFIRMATION PROCEDURE
1.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.
>> GO TO 2.
2.PERFORM DTC CONFIRMATION PROCEDURE
1. Start engine and wait maximum of 2 consecutive minutes.
2. Check 1st trip DTC.
Is 1st trip DTC detected?
YES >> Go to EC-346, "Diagnosis Procedure".
NO >> INSPECTION END
Diagnosis ProcedureINFOID:0000000005930005
1.CHECK COMBINATION METER FUNCTION
Refer to DI-14, "
Trouble Diagnosis".
Is the inspection result normal?
YES >> GO TO 2.
NO >> Refer to DI-14, "
Trouble Diagnosis"
2.CHECK INTERMITTENT INCIDENT
