Variable Induction Control Valve: Testing and Inspection

2UZ-FE INTAKE: VACUUM SWITCHING VALVE (for ACIS):

INSPECTION





1. INSPECT INTAKE AIR CONTROL VALVE
(a) With 40 kPa (300 mmHg, 11.8 in.Hg) of vacuum applied to the actuator, check that the actuator rod moves.
(b) One minute after applying the vacuum in the above step, check that the actuator rod does not return.
If the operation is not as specified, replace the intake manifold.
2. INSPECT VACUUM SWITCHING VALVE ASSEMBLY (for ACIS)





(a) Measure the resistance according to the value(s) in the table below.
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.
