Inspection [11/2021 - ]: Procedure
WARNING: This page is about a different car, the 2025 Lexus NX 250, 2024 Lexus NX 250, 2023 Lexus NX 250, and 2022 Lexus NX 250. However, it is still accessible from the selected car via links, so may be relevant.
- INSPECT NO. 2 FUEL PRESSURE SENSOR
- Check the No. 2 fuel pressure sensor output voltage.
- Apply 5 V between terminals 1 (VC) and 3 (E2).
*a Component without harness connected
(No. 2 Fuel Pressure Sensor)*b Voltage Applied between Terminals NOTE:- Be careful when connecting the leads, as the No. 2 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 No. 2 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 No. 2 fuel pressure sensor.
*a Component without harness connected
(No. 2 Fuel Pressure Sensor)
- Apply 5 V between terminals 1 (VC) and 3 (E2).
- Check the No. 2 fuel pressure sensor output voltage.
