ENGINE COOLANT TEMPERATURE SENSOR INSPECTION


  1. INSPECT ENGINE COOLANT TEMPERATURE SENSOR


    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 Approx. 20°C (68°F) 2.32 to 2.59 kΩ
      Approx. 80°C (176°F) 0.310 to 0.326 kΩ

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

      Note

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