INSPECTION
1.
REMOVE V- BANK COVER, AND EMISSION CON-
TROL VALVE SET
2.
REMOVE VSV
(a)
Disconnect the 2 vacuum hoses from the VSV.
(b)
Remove the screw and VSV.
3.
INSPECT VSV FOR OPEN CIRCUIT
Using an ohmmeter, check that there is continuity between
each terminals.
Resistance: 33 - 39
Ω
at 20
°
C (68
°
F)
If there is no continuity, replace the VSV.
4.
INSPECT VSV FOR GROUND
Using an ohmmeter, check that there is no continuity between
each terminal and the body.
If there is continuity, replace the VSV.
5.
INSPECT VSV OPERATION
(a)
Check that air flows from port E to the filter.
(b)
Apply battery voltage across the terminals.
(c)
Check that air flows from port E to port F.
If operation is not as specified, replace the VSV.
6.
REINSTALL VSV
(a)
Install the VSV with the screw.
(b)
Connect the 2 vacuum to the VSV.
7.
REINSTALL EMISSION CONTROL VALVE SET
8.
REINSTALL V-BANK COVER
