PROCEDURE


  1. READ VALUE USING GTS (ENGINE OIL TEMPERATURE)


    1. Connect the GTS to the DLC3.

    2. Turn the engine switch on (IG).

    3. Turn the GTS on.

    4. Enter following menus: Body Electrical / Combination Meter / Data List.

    5. Read the Data List according to the display on the GTS.


      Body Electrical > Combination Meter > Data List
      Tester Display Measurement Item Range Normal Condition Diagnostic Note
      Engine Oil Temperature Engine oil temperature Min.: 0°C (32°F), Max.: 255°C (491°F)

      Engine oil temperature receiver gauge indication:

      When the indicator is in the center of the gauge: 80 to 105°C (176 to 221°F)

      When the indicator is in the red zone: 140°C (284°F) or more

      Body Electrical > Combination Meter > Data List
      Tester Display
      Engine Oil Temperature
      OK
      Engine oil temperature displayed on the GTS is almost the same as the engine oil temperature receiver gauge indication.

  3. CHECK HARNESS AND CONNECTOR (COMBINATION METER ASSEMBLY - OIL TEMPERATURE SENSOR)


    1. Disconnect the K33 combination meter assembly connector.

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

      Standard Resistance
      Tester Connection Condition Specified Condition
      K33-1 (GAGE) - E7-2 (OT+) Always Below 1 Ω
      K33-24 (GND) - E7-1 (OT-) Always Below 1 Ω
      K33-1 (GAGE) - Body ground Always 10 kΩ or higher
      K33-24 (GND) - Body ground Always 10 kΩ or higher
