DTC P0453 EVAP CONTROL SYSTEM PRESSURE SENSOR
5.
Use pump to apply vacuum and pressure to EVAP control sys-
tem pressure sensor as shown in figure.
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).
6.
Check voltage between ECM terminal 110 and ground with
CONSULT-II or tester.
CAUTION:
Discard any EVAP control system pressure sensor which has dropped from a height of more than
0.5 m (19.7 in) onto a hard surface such a concrete floor; use a new one.
7.
If NG, replace EVAP control system pressure sensor.

NOTE:
If DTC P0455 is displayed with P1448, first perform trouble diagnosis for DTC P1448. (See
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
EBS00MFC
CAUTION:
Never remove fuel filler cap during the DTC Confirmation Procedure.
NOTE:
●
If DTC P0455 is displayed with P1448, first perform trouble diagnosis for DTC P1448. (See
.)
●
Make sure that EVAP hoses are connected to EVAP canister purge volume control solenoid valve
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:
●
Perform “DTC WORK SUPPORT” when the fuel level is between 1/4 and 3/4 full, and vehicle is
placed on flat level surface.
●
Open engine hood before conducting the following procedures.
WITH CONSULT-II
1.
Tighten fuel filler cap securely until ratcheting sound is heard.
2.
Turn ignition switch “ON”.
3.
Turn ignition switch “OFF” and wait at least 10 seconds.
4.
Turn ignition switch “ON” and select “DATA MONITOR” mode with CONSULT-II.
5.
Make sure that the following conditions are met.

°
C (32 - 158
°
F)
INT/A TEMP SE: 0 - 60
°
C (32 - 140
°
F)
6.
Select “EVAP SML LEAK P0442/P1442” of “EVAPORATIVE SYSTEM” in “DTC WORK SUPPORT” mode
with CONSULT-II.
Follow the instruction displayed.
