Airflow inspection
- Disconnect the negative battery terminal. (See NEGATIVE BATTERY TERMINAL DISCONNECTION/CONNECTION .)
- Remove the CV solenoid valve. (See CANISTER VENT (CV) SOLENOID VALVE REMOVAL/INSTALLATION .)
- 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 .)
- Should assume the voltage 12V(D.C.).
- Terminals A and B is nonpolar.
