Component Inspection

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.

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.

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.
