3UZ-FE INTAKE: VACUUM SWITCHING VALVE: ON-VEHICLE INSPECTION

ON-VEHICLE INSPECTION

1. INSPECT VACUUM SWITCHING VALVE ASSEMBLY (for ACIS)





(a) Measure the resistance of the VSV.
Standard resistance:





If the result is not as specified, replace the VSV assembly.
(b) Check the VSV operation.




(1) Check that air flows from port E to the filter.
If the result is not as specified, replace the VSV assembly.
(2) Apply battery voltage across the terminals.




(3) Check that air flows from port E to F.
If the result is not as specified, replace the VSV assembly.
