EGR Control Solenoid: Testing and Inspection

1. REMOVE VSV.
2. INSPECT VSV.





- Inspect VSV for open circuit
- Using an ohmmeter, check that there is continuity between the terminals.

Resistance: At 2O°C (68°F): 38.5 - 44.5 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.
3. REINSTALL VSV.
