4. VACUUM SWITCHING VALVE NO.1
(a) Inspect VSV for open circuit.
(1) Using an ohmmeter, check that there is continuity
between the terminals.
Resistance: 27 – 33 Ω at 20C (68F)
If there is no continuity, replace the VSV.
(b) Inspect VSV for ground.
(1) Using an ohmmeter, check that there is no continu-
ity between each terminal and the body.
If there is continuity, replace the VSV.
(c) Inspect VSV operation.
(1) Check that air flows from port E to port G.
(2) Apply battery positive voltage across the terminals.
(3) Check that air flows from port E to port F.
If operation is not as specified, replace the VSV.
