4. Also check harness for short to power.
Is the inspection result normal?

YES-1 >> With CONSULT: GO TO 4.

YES-2 >> Without CONSULT: GO TO 5.

NO

>> Repair or replace error-detected parts.

4.

CHECK EVAP CANISTER PURGE VOLUME CONTROL SOLENOID VALVE OPERATION

With CONSULT

GI-45, "Intermittent Incident"

.

NO

>> GO TO 5.

5.

CHECK EVAP CANISTER PURGE VOLUME CONTROL SOLENOID VALVE

Check the EVAP canister purge volume control solenoid valve. Refer to 

EC-363, "Component Inspection"

. 

Is the inspection result normal?

YES

>> Check intermittent incident. Refer to 

GI-45, "Intermittent Incident"

.

NO

>> Replace EVAP canister purge volume control solenoid valve. Refer to 

EM-29, "Exploded View"

.
