1. Disconnect the negative battery cable. (See NEGATIVE BATTERY CABLE DISCONNECTION/CONNECTION [SKYACTIV-G 2.5].)
2. Remove the CV solenoid valve. (See CANISTER VENT (CV) SOLENOID VALVE REMOVAL/INSTALLATION [SKYACTIV-G 2.5].)
3. Inspect airflow between the ports under the following conditions.
Measured condition
Continuity between A—B
When voltage is not applied between terminals A and B
Airflow detected
When voltage is applied between terminals A and B
No airflow
If not as specified, replace the CV solenoid valve. (See CANISTER VENT (CV) SOLENOID VALVE REMOVAL/INSTALLATION [SKYACTIV-G 2.5].)
Should assume the voltage 12V (D.C.).
Terminals A and B is nonpolar.
