Canister Vent Solenoid Inspection

Tools Required
J 39200 Digital Multimeter.

1. Disconnect the EVAP canister vent solenoid electrical connector.
2. Measure the resistance between the electrical terminals of the EVAP canister vent solenoid (2) with the DMM (1). The resistance should be 25 to 30 ohms at 20°C (68°F).
3. Replace the EVAP canister vent solenoid if the resistance is not 25 to 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 solenoid hose that was disconnected from the EVAP canister. Air should pass through the EVAP canister vent solenoid.
6. Connect 12 volts DC to the EVAP canister vent solenoid electrical terminals.
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 hose.
10. Reconnect the EVAP canister vent solenoid electrical connector.
