1GR-FE INTAKE: INTAKE SYSTEM:

INSPECTION





1. INSPECT INTAKE AIR SURGE TANK
(a) Inspect the diaphragm.
(1) Check that the lever moves when a vacuum of 26.6 kPa (200 mmHg) is applied with the Vacuum gage on.
(2) Check that the vacuum of 26.6 kPa (200 mmHg) is sustained for 1 minute in the above state.
2. INSPECT NO. 1 VACUUM SWITCHING VALVE ASSEMBLY





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





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:





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.
