FUEL PRESSURE SENSOR INSPECTION

PROCEDURE


  1. INSPECT NO. 2 FUEL PRESSURE SENSOR


    1. Check the fuel pressure sensor output voltage.

        *a

        Component without harness connected

        (No. 2 Fuel Pressure Sensor)
        *b Voltage Applied between Terminals

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

        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).

        Tech Tips

        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

        (No. 2 Fuel Pressure Sensor)

        Measure the voltage according to the value(s) in the table below.

        Standard Voltage
        Tester Connection Condition Specified Condition
        E16-2(PFL) - E16-3(E2) Pressure not applied to No. 2 fuel pressure sensor Approximately 0.6 to 0.9 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.
