      (Engine Coolant Temperature Sensor)

      Partially soak the sensor in the 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

      Note

      When checking the 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.
