EGR Control Solenoid: Testing and Inspection

INSPECTION

1. REMOVE V-BANK COVER, HIGH-TENSION CORD COVER AND EMISSION CONTROL VALVE SET
2. REMOVE VSV
(a) Disconnect the 3 vacuum hoses from the VSV.
(b) Remove the screw and VSV.





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

Resistance: 27-33 ohms at 20° C (68° F)

If there is no continuity, replace the VSV.





4. 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.
5. INSPECT VSV OPERATION





(a) Check that air flows from port E to port G.





(b) Apply battery voltage across the terminals.
(c) Check that air flows from port E to port F.
If operation is not as specified, replace the VSV.
6. REINSTALL VSV
(a) Install the VSV with the screw.
(b) Connect the 3 vacuum hoses to the VSV.
7. REINSTALL EMISSION CONTROL VALVE SET
8. REINSTALL HIGH-TENSION CORD COVER
9. REINSTALL V-BANK COVER
