EGR Control Solenoid: Testing and Inspection

INSPECTION





1. INSPECT [1][2][3]VSV FOR OPEN CIRCUIT
Using an ohmmeter, check that there is continuity between the terminals.

Resistance: 33-39 ohms at 20°C (68°F)

If there is no continuity, replace the [1][2][3]VSV.





2. INSPECT [1][2][3]VSV FOR GROUND
Using an ohmmeter, check that there is no continuity between each terminal and the body.
If there is continuity, replace the [1][2][3]VSV.
3. INSPECT [1][2][3]VSV OPERATION





(a) Check that air does not flow from pipe E to pipe F





(b) Apply battery voltage across the terminals.
(c) Check that air flows from pipe E to pipe F.
If operation is not as specified, replace the [1][2][3]VSV.
