COMMON RAIL INSPECTION

PROCEDURE


  1. INSPECT COMMON RAIL ASSEMBLY


    1. A00YSFUC01
      *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

        Tech Tips

        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

        Tech Tips

        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.
