Inspection [11/2021 - ]: Procedure
WARNING: This page is about a different car, the 2025 Lexus NX 350, 2024 Lexus NX 350, 2023 Lexus NX 350, and 2022 Lexus NX 350. However, it is still accessible from the selected car via links, so may be relevant.
- INSPECT VACUUM REGULATING VALVE ASSEMBLY
- 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) 11.1 to 12.5 Ω 1 - Vacuum regulating valve assembly body ground Always 10 MΩ or higher 2 - Vacuum regulating valve assembly body ground If the result is not as specified, replace the vacuum regulating valve assembly.
- Check the operation of the vacuum regulating valve assembly.
- Using a vacuum pump, apply a vacuum of 67 kPa (503 mmHg, 19.8 in. Hg) to the port (F) and check that the vacuum regulating valve operates normally.
*a Port (E) *b Port (F) *c Air - Check that air flows from the filter when air is blown into the port (E).
HINT:
When air is blown into the port (E), the vacuum of the port (F) decreases.
- Apply battery voltage between the terminals, and check that air flows from the port (F) when air is blown into the port (E).
