Exhaust Bypass Valve Vacuum Solenoid: Testing and Inspection

VACUUM SWITCHING VALVE (VSV) INSPECTION



1. REMOVE VSV.
2. INSPECT VSV.

A. Inspect VSV for open circuit.



Using an ohmmeter, check that there is continuity between the terminals.

Resistance at 20°C (68°F): 22 - 26 Ohms

^ If there is no continuity, replace the VSV.

B. 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.

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.
