Airflow inspection
- Disconnect the negative battery cable. (See NEGATIVE BATTERY CABLE 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.
