Inspection [11/2021 - ]: Procedure

WARNING: This page is about a different car, the 2025 Lexus NX 350h, 2024 Lexus NX 350h, 2023 Lexus NX 350h, and 2022 Lexus NX 350h. 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).

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.

*a	Component without harness connected (Fuel Pressure Sensor)
*b	Voltage Applied between Terminals

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.
