Canister Purge Solenoid: Testing and Inspection

Procedure
1. Disconnect the EVAP Canister Vent Solenoid valve electrical connector.
2. Using a DMM, measure the resistance of the EVAP Canister Vent Solenoid valve between both terminals. The resistance should be 25 to 30 ohms at 20° C (68° F).
3. Replace the EVAP Canister Vent Solenoid valve if the resistance is not 25 to 30 ohms at 20° C (68° F). If the resistance is within specification, proceed to step 4.
4. Disconnect the EVAP Canister Vent solenoid hose from the EVAP canister.
5. Blow air into the EVAP Canister Vent Solenoid hose that was disconnected from the EVAP canister (1). Air should pass through the EVAP Canister Vent Solenoid.
6. Connect 12 volts DC to the EVAP Canister Vent Solenoid terminals (2).
7. Blow air into the EVAP Canister Vent solenoid 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 EVAP Canister Vent Solenoid valve vacuum hoses and electrical connector.
