Inspection [08/2020 - ]: Procedure

WARNING: This page is about a different car, the 2024 Lexus ES 250, 2023 Lexus ES 250, 2022 Lexus ES 250, and 2021 Lexus ES 250. However, it is still accessible from the selected car via links, so may be relevant.
  1. INSPECT FUEL PRESSURE SENSOR 
    1. Check the fuel pressure sensor output voltage.
      1. Apply 5 V between terminals 1 (VC) and 2 (E2).
        NOTE:
        • Be careful when connecting the leads as the fuel pressure sensor may be damaged if the leads are connected to the wrong terminals.
        • Do not apply more than 6 V to terminals 1 (VC) or 2 (E2).

        HINT: 

        If a stable power supply is not available, connect 4 nickel-metal hydride batteries (1.2 V each) or equivalent in series.

      2. Measure the voltage according to the value(s) in the table below.

        Standard Voltage

        Tester Connection Condition Specified Condition
        3 (PR) - 2 (E2) Pressure not applied to fuel pressure sensor Approximately 0.4 to 0.6 V*

        *: The output voltage changes depending on the voltage applied to the terminals.

        If the result is not as specified, replace the fuel pressure sensor.
