Variable Induction Control Valve: Testing and Inspection

2GR-FE INTAKE: VACUUM SWITCHING VALVE: INSPECTION

INSPECTION

1. INSPECT VACUUM SWITCHING VALVE





(a) Measure the VSV resistance.
Standard resistance:





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




(1) When vacuum is applied to the E port, check that air is sucked into the filter.
If the result is not as specified, replace the VSV.




(2) Apply battery voltage across the terminals. When vacuum is applied to the F port, check that air is sucked into the E port.
If the result is not as specified, replace the VSV.
