WARNING: This page is about a different car, the 2016 Toyota Sienna. However, it is still accessible from the selected car via links, so may be relevant.
- INSPECT VACUUM SWITCHING VALVE
- Measure the resistance according to the value(s) in the table below.TEXT IN ILLUSTRATION
*a Component without harness connected
(Vacuum Switching Valve)*b Body Ground Standard Resistance
Tester Connection Condition Specified Condition 1 - 2 20°C (68°F) 37 to 44 Ω 1 - Body ground Always 1 MΩ or higher 2 - Body ground If the result is not as specified, replace the vacuum switching valve.
- Check the vacuum switching valve operation.
- When vacuum is applied to port E, check that air is sucked into the filter.TEXT IN ILLUSTRATION
