Inspection [12/2023 - ]: Procedure
WARNING: This page is about a different car, the 2024 Lexus TX 550h+. However, it is still accessible from the selected car via links, so may be relevant.
- INSPECT FUEL DELIVERY PIPE WITH SENSOR ASSEMBLY (FUEL PRESSURE SENSOR) 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 delivery pipe with sensor assembly (fuel pressure sensor) 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 according to the value(s) in the table below.
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 delivery pipe with sensor assembly (fuel pressure sensor).
