Vacuum Switching Valve

2GR-FE INTAKE: VACUUM SWITCHING VALVE: INSPECTION

INSPECTION

1. INSPECT VACUUM SWITCHING VALVE ASSEMBLY





(a) Inspect VSV operation.
(1) Using an ohmmeter, measure the resistance according to the value(s) in the table below.
Standard resistance:






If the result is not as specified, replace the VSV.
(b) Inspect the VSV for a short to ground.




(1) Using an ohmmeter, measure the resistance according to the value(s) in the table below.
Standard resistance:






If the result is not as specified, replace the VSV.





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