On-Vehicle 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.
  1. INSPECT NO. 2 TURBO PRESSURE SENSOR 
    1. Check the terminal voltage.
      1. Disconnect the No. 2 turbo pressure sensor connector.
      2. Measure the voltage according to the value(s) in the table below.

        Standard Voltage

        Tester Connection Condition Specified Condition
        B72-3 (VC) - B72-2 (E2) Ignition switch ON 4.5 to 5.5 V
        B72-1 (PTA) - B72-2 (E2) 3.0 to 5.5 V

        If the result is not as specified, repair or replace the wire harness or connector.

    2. Check the turbo pressure.
      1. Turn the ignition switch to ON.
      2. According to the display on the GTS read the Data List.

        OK

        The value is approximately equal to atmospheric pressure.

        HINT: 

        • Standard atmospheric pressure is approximately 101 kPa (abs) (15 psi (abs)).
        • For every 100 m (328 ft) increase in altitude, atmospheric pressure drops by approximately 1 kPa (0.15 psi). This varies by weather.
