EXHAUST MANIFOLD W/ TURBOCHARGER INSPECTION

PROCEDURE


  1. INSPECT TURBOCHARGER SUB-ASSEMBLY


    1. Check the resistance.


      1. A00Y54EC03
        *a

        Component without harness connected

        (Turbocharger Sub-assembly)

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

        Standard Resistance
        Tester Connection Condition Specified Condition
        1 (M-) - 2 (M+) Always 0.3 to 100 Ω

        If the result is not as specified, replace the turbocharger sub-assembly.

  2. VISUALLY CHECK TURBOCHARGER SUB-ASSEMBLY


    1. A00Y6Z4C02
      *1 Turbine Wheel

      Check for deformation or cracks in the turbine wheel on the exhaust side.

      If the turbine wheel is cracked or deformed, replace the turbocharger sub-assembly.

  3. CHECK TURBOCHARGER SUB-ASSEMBLY


    1. A00YAO7

      Rotate the turbine wheel on the exhaust side by hand and check that it rotates smoothly.

      Tech Tips

      Even if it takes a little effort to rotate the turbine wheel, this is not a problem.

      If the turbine wheel does not rotate smoothly, replace the turbocharger sub-assembly.

    2. A00Y60V

      Move the turbine wheel as shown in the illustration and check that there is no looseness in the shaft and that it does not contact the housing.

      If there is any contact with the housing or obvious looseness in the shaft, replace the turbocharger sub-assembly.

      Tech Tips

      Clearance on the order of 100 μm exists between the turbine shaft and bearings. If it is difficult to judge the looseness of the turbine shaft, perform the same inspection on another vehicle which has the same turbocharger sub-assembly and compare the clearance.
