Variable Induction Check Valve: Testing and Inspection

COMPONENTS

INSPECTION

1. REMOVE V-BANK COVER
2. REMOVE INTAKE AIR CONNECTOR PIPE
3. DISCONNECT THROTTLE BODY FROM INTAKE MANIFOLDS
4. REMOVE UPPER AND LOWER INTAKE MANIFOLDS ASSEMBLY
5. REMOVE VSV

6. INSPECT VSV




a. Inspect the VSV for open circuit.
Using an ohmmeter, check that there is continuity between each terminals.
Resistance: 33-39° C at 20° C (68° F)
If there is no continuity, replace the VSV.




b. Inspect the 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.

c. Inspect the VSV operation.




1. Check that air flows from port E to the filter.




2. Apply battery positive voltage across the terminals.
3. Check that air flows from ports E to F.
If operation is not as specified, replace the VSV.

7. REINSTALL VSV
8. REINSTALL UPPER AND LOWER INTAKE MANIFOLDS ASSEMBLY
9. REINSTALL THROTTLE BODY TO INTAKE MANIFOLDS
10. REINSTALL INTAKE AIR CONNECTOR PIPE
11. REINSTALL V-BANK COVER
