EGR Control Solenoid: Testing and Inspection

INSPECTION





1. REMOVE VSV
(a) Disconnect the connector, wire clamp and 3 EVAP hoses from the VSV.
(b) Remove the bolt and VSV.





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

Resistance: At 20°C (68°F): 37 - 44 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.
It there is continuity, replace the VSV.
4. INSPECT VSV OPERATION





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





(b) Apply battery voltage across the terminals.
(c) Check that air flows from ports E to F and does not flow from ports E to P.
If operation is not as specified, replace the VSV.
5. REINSTALL VSV
