ENGINE COOLANT TEMPERATURE SENSOR INSPECTION

PROCEDURE


  1. INSPECT ENGINE COOLANT TEMPERATURE SENSOR

    A00YNT5

    1. Partially immerse the engine coolant temperature sensor in water and warm up the water.

    2. 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) 2.32 to 2.59 kΩ
      1 - 2 80°C (176°F) 0.310 to 0.326 kΩ

      Note

      When checking the engine coolant temperature sensor in water, keep the terminals dry. After the check, wipe the sensor dry.

      If the result is not as specified, replace the engine coolant temperature sensor.
