Inspect Vacuum Switching Valve Assembly
- Using an ohmmeter, check that there is continuity between each terminal. Resistance: 33 to 39 Ω at 20°C (68°F)
- If there is no continuity, replace the VSV.
- Using an ohmmeter, check that there is no continuity between each terminal and the body. Resistance: 10 kΩ or higher . If there is continuity, replace the VSV.
- Check that air flows from port E to the filter.
- Apply battery voltage across the terminals.
- Check that air flows from port E to port F. If operation is not as specified, replace the VSV.
