Inspection [01/2017 - ]: Procedure

  1. INSPECT FUEL DELIVERY PIPE SUB-ASSEMBLY (FUEL PRESSURE SENSOR) 
    NOTE:
    • 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.
    1. Check the fuel pressure sensor output voltage.
      1. 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) and 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.

      2. Measure the voltage between terminals.

        Standard Voltage

        Tester Connection Condition Specified Condition
        2 (PFL) - 3 (E2) Pressure not applied to fuel pressure sensor Approximately 0.56 to 0.94 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 sub-assembly (fuel pressure sensor).
