4. Turn ignition switch ON and check output voltage between ECM

terminals under the following conditions.

CAUTION:

• Always calibrate the vacuum pump gauge when using it.
• Never apply below -93.3 kPa (-0.952 kg/cm

2

, -13.53 psi) or pressure over 101.3 kPa (1.033 kg/cm

DRAIN FILTER

1. Check visually for insect nests in the drain filter air inlet.
2. Check visually for cracks or flaws in the appearance.
3. Check visually for cracks or flaws in the hose.
4. Blow air into port A and check that it flows freely out of port B.
5. Block port B.
6. Blow air into port A and check that there is no leakage.
7. If NG, replace drain filter.

DTC DETECTION LOGIC

This diagnosis detects a very large leakage (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 illuminate.

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

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

DTC CONFIRMATION PROCEDURE

PRECONDITIONING

DTC No.

Trouble diagnosis name

DTC detecting condition

Possible cause

P0455

EVAP control system 
gross leakage detected

EVAP control system has a very large leakage 
such as fuel filler cap fell off, EVAP control sys-
tem does not operate properly.

• Fuel filler cap remains open or fails to 

close.

• Incorrect fuel tank vacuum relief valve
• Incorrect fuel filler cap used
• Foreign matter caught in fuel filler cap.
• Leakage is in line between intake mani-

fold and EVAP canister purge volume 
control solenoid valve.

• Foreign matter caught in EVAP canister 

vent control valve.

• EVAP canister or fuel tank leakage
• EVAP purge line (pipe and rubber tube) 

leakage

• EVAP purge line rubber tube bent.
• Loose or disconnected rubber tube
• EVAP canister vent control valve and the 

circuit

• Drain filter
• EVAP canister purge volume control so-

lenoid valve and the circuit

• Fuel tank temperature sensor
• O-ring of EVAP canister vent control 

valve is missing or damaged.

• EVAP control system pressure sensor
• Refueling EVAP vapor cut valve
