>>Repair open circuit, short to ground or short to power in harness or connectors.
3.CHECK EVAP CANISTER PURGE VOLUME CONTROL SOLENOID VALVE OUTPUT SIGNAL CIRCUIT FOR OPEN AND SHORT

1. Turn ignition switch OFF.
2. Disconnect ECM harness connector.
3. Check the continuity between EVAP canister purge volume control solenoid valve harness connector and ECM harness connector.

   EVAP canister purge volume control solenoid valve | ECM | Continuity
   Connector | Terminal | Connector | Terminal
   F13 | 2 | F101 | 8 | Existed

4. Also check harness for short to ground and short to power.

Is the inspection result normal?
YES>>GO TO 4.
NO>>Repair open circuit, short to ground or short to power in harness or connectors.
4.CHECK EVAP CONTROL SYSTEM PRESSURE SENSOR CONNECTOR

1. Disconnect EVAP control system pressure sensor harness connector.
2. Check that water is not inside connectors.

Is the inspection result normal?
YES>>GO TO 5.
NO>>Replace EVAP control system pressure sensor.
5.CHECK EVAP CONTROL SYSTEM PRESSURE SENSOR
Refer to Component Inspection (GT-R certified NISSAN dealer).
Is the inspection result normal?
YES-1>>With CONSULT-III: GO TO 6.
YES-2>>Without CONSULT-III: GO TO 7.
NO>>Replace EVAP control system pressure sensor.
6.CHECK EVAP CANISTER PURGE VOLUME CONTROL SOLENOID VALVE
With CONSULT-III

1. Turn ignition switch OFF.
2. Reconnect harness connectors disconnected.
3. Start engine.
4. Perform “PURG VOL CONT/V” in “ACTIVE TEST” mode with CONSULT-III. Check that engine speed varies according to the valve opening.

Does engine speed vary according to the valve opening?
YES>>GO TO 8.
NO>>GO TO 7.
7.CHECK EVAP CANISTER PURGE VOLUME CONTROL SOLENOID VALVE
Refer to Component Inspection (GT-R certified NISSAN dealer).
Is the inspection result normal?
YES>>GO TO 8.
NO>>Replace EVAP canister purge volume control solenoid valve.
8.CHECK RUBBER TUBE FOR CLOGGING

1. Disconnect rubber tube connected to EVAP canister vent control valve.
2. Check the rubber tube for clogging.

Is the inspection result normal?
YES>>GO TO 9.
NO>>Clean the rubber tube using an air blower.
9.CHECK EVAP CANISTER VENT CONTROL VALVE
Refer to Component Inspection (GT-R certified NISSAN dealer).
Is the inspection result normal?
YES>>GO TO 10.
NO>>Replace EVAP canister vent control valve.
10.CHECK IF EVAP CANISTER IS SATURATED WITH WATER

1. Remove EVAP canister with EVAP canister vent control valve and EVAP control system pressure sensor attached.
2. Check if water will drain from EVAP canister (1).

   2 | : EVAP canister vent control valve

Does water drain from the EVAP canister?
YES>>GO TO 11.
NO>>GO TO 13.
11.CHECK EVAP CANISTER
Weigh the EVAP canister with the EVAP canister vent control valve and EVAP control system pressure sensor attached.
The weight should be less than 2.1 kg (4.6 lb).
Is the inspection result normal?
YES>>GO TO 13.
NO>>GO TO 12.
12.DETECT MALFUNCTIONING PART
Check the following.

- EVAP canister for damage
- EVAP hose between EVAP canister and vehicle frame for clogging or poor connection

>>Repair hose or replace EVAP canister.
13.CHECK INTERMITTENT INCIDENT
Refer to Intermittent Incident.
>>INSPECTION END
