INSPECT VACUUM SWITCHING VALVE ASSY NO.1
Inspect VSV for open circuit.
(1) Using an ohmmeter, measure resistance between
the terminals.
Resistance: 26 to 30 f at 20YC (68YF)
Inspect the VSV for ground.
(1) Using an ohmmeter, check that there is no continu-
ity between each terminal and the body.
Inspect the VSV operation.
(1) Check that air flows with a little difficulty from port E
to port F.
(2) Apply battery voltage across the terminals.
(3) Check that air flows from port E to port F.
