1.CHECK EVAP CANISTER PURGE VOLUME CONTROL SOLENOID VALVE POWER SUPPLY CIRCUIT

1. Turn ignition switch OFF.
2. Disconnect EVAP canister purge volume control solenoid valve harness connector.
3. Turn ignition switch ON.
4. Check the voltage between EVAP canister purge volume control solenoid valve harness connector and ground.

   EVAP canister purge volume control solenoid valve | Ground | Voltage
   Connector | Terminal
   F13 | 1 | Ground | Battery voltage

Is the inspection result normal?
YES>>GO TO 3.
NO>>GO TO 2.
2.DETECT MALFUNCTIONING PART
Check the following.

- Harness connectors E106, M6
- Harness connectors M116, F103
- Harness for open or short between EVAP canister purge volume control solenoid valve and IPDM E/R
- Harness for open or short between EVAP canister purge volume control solenoid valve and ECM

>>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-1>>With CONSULT-III: GO TO 4.
YES-2>>Without CONSULT-III: GO TO 5.
NO>>Repair open circuit, short to ground or short to power in harness or connectors.
4.CHECK EVAP CANISTER PURGE VOLUME CONTROL SOLENOID VALVE OPERATION
With CONSULT-III

1. Reconnect all harness connectors disconnected.
2. Start engine.
3. 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 6.
NO>>GO TO 5.
5.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 6.
NO>>Replace EVAP canister purge volume control solenoid valve.
6.CHECK INTERMITTENT INCIDENT
Refer to Intermittent Incident.
