Inspection [10/2017 - ]: Procedure
WARNING: This page does not describe the selected car, but rather 14 other vehicles, including the 2024 Lexus IS 350, 2024 Lexus IS 300, 2023 Lexus IS 350, 2023 Lexus IS 300, and 2022 Lexus IS 350. However, it is still accessible from the selected car via links, so may be relevant.
- INSPECT FUEL PRESSURE SENSOR (FUEL DELIVERY PIPE WITH SENSOR ASSEMBLY) NOTE:
- Do not remove the fuel pressure sensor from the fuel delivery pipe with sensor assembly.
- If the fuel pressure sensor is removed, replace the fuel pressure sensor (fuel delivery pipe with sensor assembly) with a new one.
- Check the fuel pressure sensor output voltage.
- Apply 5 V between terminals 1 (VC) and 3 (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 3 (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 between terminals.
*a Component without harness connected
(Fuel Pressure Sensor)Standard Voltage
Tester Connection Condition Specified Condition 2 (PFL) - 3 (E2) Pressure not applied to fuel pressure sensor Approximately 0.57 to 0.95 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 (fuel delivery pipe with sensor assembly).
- Apply 5 V between terminals 1 (VC) and 3 (E2).
