1986 TOYOTA SUPRA Service Repair Manual

C. Inspect VSV operation
(a) Check that air does not flow from port E to F.
(b) Apply battery voltage across the terminals.
(c) Check that air flows from port E to F.
If operation is not as specified, replace the VSV.
3. REINSTALL VSV ASSEMBLY
VSV FOR EXHAUST GAS CONTROL
VA LV E
COMPONENTS FOR REMOVAL AND
INSTALLATION
± ENGINESFI SYSTEM (2JZ±GTE)EG±305

VSV INSPECTION
1. REMOVE VSV ASSEMBLY
2. INSPECT VSV
A. Inspect VSV for open circuit
Using an ohmmeter, check that there is continuity between
the terminals.

If there is no continuity, replace the VSV.
B. Inspect VSV for ground
Using an ohmmeter, check that there is no continuity be-
tween each terminal and the body.
If there is continuity, replace the VSV.
C. 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 F.
If operation is not as specified, replace the VSV.
3. REINSTALL VSV ASSEMBLY EG±306

If there is no continuity, replace the VSV.
B. Inspect VSV for ground
Using an ohmmeter, check that there is no continuity be-
tween each terminal and the body.
If there is continuity, replace the VSV.
C. Inspect VSV operation
(a) Check that air does not flow from port E to F.
(b) Apply battery voltage across the terminals.
(c) Check that air flows from port E to F.
If operation is not as specified, replace the VSV.
