WARNING: This page is about a different car, the 2006 Lexus IS 350. However, it is still accessible from the selected car via links, so may be relevant.

INSPECT FUEL PRESSURE SENSOR
1. Check the fuel pressure sensor output voltage.
  1. Apply 5 V between terminals 3 (VC) and 1 (E2).
  2. Measure the voltage between terminals 2 (PR) and 1 (E2).

    Standard voltage: Approximately 0.5 V
    
    HINT:
    
    The above voltage is output when pressure is not applied (0 kPa (0 kgf*cm² )) to the sensor.
