      Condition

      Specified Condition

      1 - 2

      20°C (68°F)

      2.32 to 2.59 kΩ

      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 engine coolant temperature sensor dry.

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