EGR Control Solenoid: Testing and Inspection

INSPECTION





1. REMOVE [1][2][3]VSV
(a) Remove the bolt.
(b) Disconnect the connector and 2 vacuum hoses from the [1][2][3]VSV.





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

Resistance:
33 - 39 ohms at 20°C (68°F)

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





3. 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.
4. INSPECT [1][2][3]VSV OPERATION





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





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