COMMON RAIL INSPECTION

PROCEDURE


  1. INSPECT COMMON RAIL ASSEMBLY


    1. Inspect the fuel pressure sensor.


      1. A00Y5WKC01
        *a

        Component without harness connected

        (Fuel Pressure sensor)

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

        Tech Tips

        Perform the inspection with no fuel pressure applied.

        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

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

    2. Inspect the pressure control valve.


      1. A00Y53AC02
        *a

        Component without harness connected

        (Pressure Control Valve)

        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

        Tech Tips

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

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