Inspection [10/2018 - ]: Procedure
WARNING: This page does not describe the selected car, but rather 6 other vehicles, including the 2024 Lexus UX 250h, 2023 Lexus UX 250h, 2022 Lexus UX 250h, 2021 Lexus UX 250h, and 2020 Lexus UX 250h. However, it is still accessible from the selected car via links, so may be relevant.
- INSPECT FUEL PRESSURE SENSOR
- Check the fuel pressure sensor output voltage.
- Apply 5 V between terminals 1 (VC) and 2 (E2).

*a Component without harness connected
(Fuel Pressure Sensor)*b Voltage Applied between Terminals 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.
- 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.
*a Component without harness connected
(Fuel Pressure Sensor)
- Apply 5 V between terminals 1 (VC) and 2 (E2).
- Check the fuel pressure sensor output voltage.
