Component Inspection

VACUUM SWITCHING VALVE (VSV) FOR ACIS INSPECTION

1. Remove V-Bank cover and emission
control valve set and high-tension cord cover.
2. Remove VSV
(a) Disconnect the 2 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 each terminals.

Resistance: 33 - 39 ohm at 2O°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 the filter.
(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 2 vacuum to the VSV.
7. Reinstall emission control valve set.
8. Reinstall high-tension cord cover.
9. Reinstall V-Bank cover.
