Power Steering Vacuum Switching Valve (VSV)

  1. Turn ignition off. Disconnect power steering VSV connector. Check resistance of VSV at connector terminals. Resistance should be 33-39 ohms. Replace VSV if resistance is not correct. If resistance is okay, remove vacuum hoses from VSV.
  2. Blow air into one VSV vacuum fitting. Air should not pass through VSV. If air passes through VSV, replace VSV. Apply battery voltage and ground to VSV connector terminals. Air should pass through VSV. If air does not pass through VSV, replace VSV.
