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.
• Never apply below -93.3 kPa (-0.952 kg/cm

2

, -13.53 psi) or

pressure over 101.3 kPa (1.033 kg/cm

2

, 14.59 psi).

4.

If NG, replace EVAP control system pressure sensor.

On Board Diagnosis Logic

INFOID:0000000005273693

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 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

INFOID:0000000005273694

CAUTION:

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

DTC No.
