EGR Control Solenoid: Testing and Inspection

1. REMOVE AIR INTAKE CHAMBER.
2. INSPECT VSV.





3. DISCONNECT VACUUM HOSES AND CONNECTOR.
4. INSPECT VSV FOR OPEN CIRCUIT.





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

Resistance: At 20°C (68°F): 30 - 34 Ohms

- If there is no continuity, replace the VSV.

5. 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.
6. INSPECT VSV OPERATION.





- Check that the air flows from pipe G to pipe E.





- Apply battery voltage across the terminals.
- Check that the air does not flow from pipe G to pipe E.
- If operation is not as specified, replace the VSV.
7. CONNECT VACUUM HOSES AND CONNECTOR.
8. REINSTALL AIR INTAKE CHAMBER.
