Lexus RX (RX 350L, RX450h) 2016-2025 Repair Manual / Engine & Hybrid System / 2gr-fks (fuel) / Fuel Pressure Sensor / Inspection

INSPECTION

PROCEDURE

1. INSPECT FUEL DELIVERY PIPE SUB-ASSEMBLY (FUEL PRESSURE SENSOR)

NOTICE:

  • Do not remove the fuel pressure sensor from the fuel delivery pipe sub-assembly.
  • If the fuel pressure sensor is removed, replace the fuel delivery pipe sub-assembly (fuel pressure sensor) with a new one.

(a) Check the fuel pressure sensor output voltage.

(1) Apply 5 V between terminals 1 (VC) and 3 (E2).

NOTICE:

  • 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.
