Canister Purge Solenoid: Testing and Inspection

VSV For Evaporative Emission (EVAP)




COMPONENTS FOR REMOVAL AND INSTALLATION

VSV INSPECTION:
1. REMOVE V-BANK COVER AND EMISSION CONTROL VALVE SET.
2. REMOVE VSV.
- Disconnect the 2 EVAP hoses from the VSV.
- Remove the screw and VSV.
3. INSPECT VSV.
- Inspect VSV for open circuit




- Using an ohmmeter, check that there is continuity between the terminals.

Resistance: At 2O°C (68°F): 27 - 33 Ohms

- If there is no continuity, replace the VSV.
- Inspect VSV for ground




- Using an ohmmeter, check that there is no continuity between each terminal and the body.
- If there is continuity. replace the VSV.
- Inspect VSV operation




- Check that air does not flow from port E to F.
- Apply battery positive voltage across the terminals.




- Check that air flows from port E to F.
- If operation is not as specified, replace the VSV.
4. REINSTALL VSV.
- Install the VSV with the screw.
- Connect the 2 EVAP hoses to the VSV.
5. REINSTALL EMISSION CONTROL VALVE SET.
6. REINSTALL V-BANK COVER.
