(5)
While holding the air inlet port closed, apply vacuum
(3.43 kPa, 25.7 mmHg, 1.01 in.Hg) to the EVAP port
and check that air flows into the purge port.
(6)
Remove the hose and cap from vent port.
Inspect VSV for pressure switching valve
(1)
Using an ohmmeter, check that there is continuity
between the terminals.
Resistance:
37 – 44 Ω at 20_C (68_F)
51 – 62 Ω at 120_C (248_F)
(2)
Using an ohmmeter, check that there is no continu-
ity between each terminal and the body.
(3)
Check that air does not flow from ports E to F.
(4)
Apply battery positive voltage across the terminals.
(5)
Check that air flows from ports E to F.
