EGR Control Solenoid: Testing and Inspection

VSV INSPECTION

1. REMOVE AIR INTAKE CHAMBER
2. INSPECT VSV





A. DISCONNECT VACUUM HOSES AND CONNECTOR
B. 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.
C. 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.
D. 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 flows from pipe G to pipe E.
- If operation is not as specified, replace the VSV.
E. CONNECT VACUUM HOSES AND CONNECTOR
3. REINSTALL AIR INTAKE CHAMBER
