EGR Control Solenoid: Testing and Inspection

VSV INSPECTION:



1. REMOVE VSV.
2. INSPECT VSV FOR OPEN CIRCUIT.



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

Resistance (Cold): 33 - 39 Ohms

- If there is no continuity, replace the VSV.

3. 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.

4. INSPECT VSV OPERATION.



- Check that air flows from port E to port G.



- Apply battery voltage across the terminals.
- Check that air flows from port E to the filter.

- If operation is not as specified, replace the VSV.

5. REINSTALL VSV.
