EVAP CONTROL SYSTEM PRESSURE SENSOR

1.

Remove EVAP control system pressure sensor with its harness connector connected from EVAP canister.
Always replace O-ring with a new one.

2.

Install a vacuum pump to EVAP control system pressure sensor.

3.

Turn ignition switch ON and check output voltage between ECM
terminal 32 and ground under the following conditions.

CAUTION:

• Always calibrate the vacuum pump gauge when using it.
• Do not apply below -93.3 kPa (-700 mmHg, -27.56 inHg) or

pressure over 101.3 kPa (760 mmHg, 29.92 inHg).

4.

If NG, replace EVAP control system pressure sensor.

DTC P0455 EVAP CONTROL SYSTEM

DTC P0455 EVAP CONTROL SYSTEM

On Board Diagnosis Logic

INFOID:0000000001326219

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.

DTC Confirmation Procedure

INFOID:0000000001326220

CAUTION:

Never remove fuel filler cap during the DTC Confirmation Procedure.
NOTE:

DTC No.
