WARNING: This page is about a different car, the 2020 Mazda CX-30. However, it is still accessible from the selected car via links, so may be relevant.
- Disconnect the negative battery terminal. (See NEGATIVE BATTERY TERMINAL DISCONNECTION/CONNECTION (US) .)
- 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 ports 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 voltage12 V (D.C.).
- Terminals A and B is nonpolar.
