EVAP Canister Vent Solenoid Inspection

1. Disconnect the electrical connector from the EVAP-canister vent solenoid.
2. Use the DMM in order to measure the resistance between the electrical terminals of the EVAP-canister vent solenoid (2). The resistance should be 25-30 ohms at 20°C (68°F).
3. Replace the EVAP-canister vent solenoid if the resistance is not 25-30 ohms at 20°C (68°F). Proceed to step 4 if the resistance is within the specification.




4. Disconnect the EVAP-canister vent solenoid hose from the EVAP canister.
5. Blow air into the EVAP-canister vent hose that is disconnected from the EVAP canister. Air should pass through the EVAP-canister vent solenoid.




6. Connect 12 volts DC to the electrical terminals of the EVAP canister vent solenoid.
7. Blow air into the EVAP-canister vent vacuum hose that was disconnected from the EVAP canister. Air should not pass through the EVAP-canister vent solenoid and exit from the other end.
8. Replace the EVAP-canister vent solenoid, if the EVAP-canister vent solenoid failed this inspection.
9. Reconnect the hose to the EVAP-canister vent solenoid.
10. Reconnect the electrical connector to the EVAP-canister vent solenoid.
