EGR Control Solenoid: Testing and Inspection

COMPONENTS FOR REMOVAL AND INSTALLATION

VSV INSPECTION
1. REMOVE V-BANK COVER AND EMISSION CONTROL VALVE SET
2. REMOVE VSV
- Remove the filter.
- Disconnect the 2 vacuum 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): 33 - 39 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 flows from port E to G.
- Apply battery positive voltage across the terminals.




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