FUEL SUPPLY PUMP(w/o Glow Plug Controller) INSPECTION

PROCEDURE

  1. INSPECT SUPPLY PUMP ASSEMBLY

    A298117C01

    *a

    Component without harness connected

    (Suction Control Valve)

    *b

    Component without harness connected

    (Fuel Temperature Sensor)

    1. Inspect the resistance of the suction control valve.

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

        Standard Resistance

        Terminals

        Condition

        Resistance

        1 - 2

        20°C (68°F)

        2.60 to 3.15 Ω

        If the result is not as specified, replace the supply pump assembly.

    2. Inspect the resistance of the fuel temperature sensor.

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

        Standard Resistance

        Terminals

        Condition

        Resistance

        1 - 2

        -20°C (-4°F)

        13.92 to 17.01 kΩ

        1 - 2

        0°C (32°F)

        5.31 to 6.49 kΩ

        1 - 2

        20 °C (68°F)

        2.25 to 2.75 kΩ

        1 - 2

        40°C (104°F)

        1.06 to 1.29 kΩ

        1 - 2

        60°C (140°F)

        0.54 to 0.66 kΩ

        1 - 2

        80 °C (176°F)

        0.29 to 0.36 kΩ

        1 - 2

        100°C (212°F)

        0.17 to 0.20 kΩ

        If the result is not as specified, replace the supply pump assembly.
