EGR Control Solenoid: Testing and Inspection

VSV FOR EGR - INSPECTION



1. REMOVE VSV.
2. INSPECT VSV.
(a) Inspect VSV for open circuit.



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

Resistance @ 20°C (68°F): 33 - 39 Ohms

- If there is no continuity, replace the VSV.

(b) 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.

(c) Inspect VSV operation.



- Check that air flows from ports 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.

3. REINSTALL VSV.
