      Standard Resistance

      Tester Connection Condition Specified Condition
      1 - 2 Approx. 20°C (68°F) 2.32 k to 2.59 kΩ
      1 - 2 Approx. 80°C (176°F) 0.310 k to 0.326 kΩ

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

      NOTE:

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