Variable Induction Control Valve: Testing and Inspection

1GR-FE INTAKE: VACUUM SWITCHING VALVE:

INSPECTION

1. INSPECT NO. 1 VACUUM SWITCHING VALVE ASSEMBLY





(a) Check the resistance.
(1) Using an ohmmeter, measure the resistance between the terminals.
Standard resistance:






If the result is not as specified, replace the vacuum switching valve No. 1.






(b) Check the vacuum switching valve No. 1 for ground.
(1) Using an ohmmeter, measure the resistance between each terminal and the body.
Standard resistance:






If the result is not as specified, replace the vacuum switching valve No. 1.
(c) Check the operation.





(1) Check that air does not flow from port E to port F.
If the operation is not as specified, replace the vacuum switching valve No. 1.





(2) Apply battery voltage across the terminals.
(3) Check that air flows from port E to port F.
If the operation is not as specified, replace the vacuum switching valve No. 1.
