    2. Remove the air filter element sub-assembly.

    3. Visually check that the air cleaner filter element sub-assembly is not excessively damaged or oily. If necessary, replace the air cleaner filter element sub-assembly.

      Tip:

      • If there is any foreign matter or clogs in the air cleaner filter element sub-assembly, clean it with compressed air.

      • If any foreign matter or clogs remain even after cleaning the air cleaner filter element sub-assembly with compressed air, replace it.

    4. Install the air cleaner filter element sub-assembly.

    5. Install the air cleaner cap sub-assembly.

  6. INSPECT ENGINE SPEED

    Note:

    • Turn all the electrical systems and the A/C off.

    • Inspect the engine idle speed with the cooling fan off.

    • When checking the idle speed, the transaxle should be in neutral.

    1. Warm up and stop the engine.

    2. When using the GTS:

      1. Connect the GTS to the DLC3.

      2. Turn the ignition switch to ON.

      3. Start the engine.

      4. Turn the GTS on.

      5. Enter the following menus: Powertrain / Engine and ECT / Data List / Engine Speed.

        Powertrain > Engine and ECT > Data List
        Tester Display
        Engine Speed

      6. Inspect the engine idle speed.

        Standard Idle Speed
        720 to 820 rpm

      7. Fully depress the accelerator pedal.

      8. Inspect the maximum engine speed.

        Maximum Speed
        5150 to 5250 rpm

      9. Turn the ignition switch off.

      10. Disconnect the GTS from the DLC3.

    3. A012IE4N01

      When not using the GTS:

      1. Using SST, connect a tachometer probe to terminal 9 (TAC) of the DLC3.

        SST
        09843-18040
        Note:

        Be sure to connect the tachometer to the correct terminal. Connecting the wrong terminals can cause damage.

      2. Turn the ignition switch to ON.

      3. Start the engine.

      4. Inspect the engine idle speed.

        Standard Idle Speed
        720 to 820 rpm

      5. Fully depress the accelerator pedal.

      6. Inspect the maximum engine speed.

        Maximum Speed
        5150 to 5250 rpm

      7. Turn the ignition switch off.

      8. Disconnect the tachometer probe from terminal 9 (TAC) of the DLC3.

  7. INSPECT COMPRESSION

    1. Warm up and stop the engine.

    2. Disconnect the 4 connectors from the 4 injector assemblies.

      A012LFV

    3. Remove the 4 glow plug assemblies.

      Note:

      In order to avoid shorting the circuit of the wire harness connected to the glow plug No. 1 connector, wind vinyl tape around the wire harness terminal portion.

    4. Remove the bolt and separate the No. 3 engine cover bracket.

      A012FOP

    5. Connect the cable to the negative (-) battery terminal.

    6. Crank the engine to remove foreign matter before measuring the compression.

    7. Install the SST (attachment) into the glow plug assembly hole.

      A012ISIC02
      *a SST (Attachment)
      SST
      09992-00026   ( 09992-00121, 09992-00160 )
      Момент затяжки
      13 N*m  { 133 kgf*cm, 10 ft.*lbf }

    8. Connect a SST (compression gauge) to the SST (attachment).

      A012I0FC02
      *a SST (Compression Gauge)
      SST
      09992-00026   ( 09992-00211 )

    9. While cranking the engine, measure the compression pressure.

      Compression Pressure
      2300 kPa (23.5 kgf/cm2, 334 psi)
      Minimum Pressure
      2050 kPa (20.9 kgf/cm2, 297psi)
      Difference Between Each Cylinder
      500 kPa (5.1 kgf/cm2, 73 psi) or less
      Note:

      • Use a fully-charged battery so that the engine speed can be increased to 250 rpm or more.

      • Inspect the other cylinders in the same way.

      • Measure the compression pressure in as short a time as possible.

      If the cylinder compression is low, pour a small amount of engine oil into the cylinder through the glow plug assembly hole, and then inspect it again.

      Tip:

      • If adding oil increases the compression, the piston rings and/or cylinder bore may be worn or damaged.

      • If the compression pressure stays low, a valve may be stuck or seated improperly, or there may be leaks in the cylinder head gasket.

    10. Remove the SST (compression gauge and attachment).

    11. Install the No. 3 engine cover bracket with the bolt.

      Момент затяжки
      9.0 N*m  { 92 kgf*cm, 80 in.*lbf }

    12. Install the 4 glow plug assemblies.
