EGR Control Solenoid: Testing and Inspection

COMPONENTS

INSPECTION

1. REMOVE V-BANK COVER AND EMISSION CONTROL VALVE SET AND HIGH-TENSION CORD COVER

2. REMOVE [1][2][3]VSV
a. Disconnect the 3 vacuum hoses from the VSV.
b. Remove the screw and [1][2][3]VSV.

3. INSPECT [1][2][3]VSV FOR OPEN CIRCUIT




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

Resistance:
27 - 33 at 20°C (68°F)

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

4. 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.

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




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




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

6. REINSTALL [1][2][3]VSV
a. Install the VSV with the screw.
b. Connect the 3 vacuum hoses to the [1][2][3]VSV.

7. REINSTALL EMISSION CONTROL VALVE SET
8. REINSTALL HIGH-TENSION CORD COVER
9. REINSTALL V-BANK COVER
