Exhaust Control Valve Vacuum Solenoid: Testing and 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): 38.5 - 44.5 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.



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



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

3. REINSTALL VSV.
