2. Disconnect the 2 vacuum hoses from the vacuum switching valve assembly (for AICV).
3. Measure the resistance according to the value(s) in the table below.

   Standard Resistance

   Tester Connection	Condition	Specified Condition
   1 - 2	20°C (68°F)	37 to 44 Ω
   D27-1 - Body ground	Always	10 kΩ or higher
   D27-2 - Body ground	Always	10 kΩ or higher

   *a	Component without harness connected (Vacuum Switching Valve Assembly (for AICV))
   *b	Body Ground

   If the result is not as specified, replace the air cleaner assembly.

4. Check the operation of the vacuum switching valve assembly (for AICV).
   1. When vacuum is applied to the port (E), check that air is sucked into the filter.

      If air is not sucked into the filter, replace the air cleaner assembly.
