COMMON RAIL INSPECTION

PROCEDURE

  1. INSPECT COMMON RAIL ASSEMBLY

    1. A114886C01

      *a

      Component without harness connected

      (Fuel Pressure sensor)

      Inspect the fuel pressure sensor.

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

        Standard Resistance

        Tester Connection

        Condition

        Specified Condition

        5 (PR) - 4 (E2)

        Always

        16.4 kΩ or less

        2 (PR2) - 3 (E2S)

        Always

        16.4 kΩ or less

        6 (VC) - 5 (PR)

        Always

        3 kΩ or less

        1 (VCS) - 2 (PR2)

        Always

        3 kΩ or less
        Tip:

        Perform the inspection with no fuel pressure applied.

        If the result is not as specified, replace the common rail assembly.

    2. Inspect the pressure discharge valve.

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

        Standard Resistance

        Tester Connection

        Condition

        Specified Condition

        1 - 2

        20°C (68°F)

        0.96 to 1.16 Ω
        Tip:

        The temperature indicated in "Condition" is the temperature of the pressure discharge valve.

        If the result is not as specified, replace the common rail assembly.
