      (Engine Coolant Temperature Sensor)

      		 *b Resistance
      *c Temperature *d Acceptable Range
      Standard Resistance
      Tester Connection 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

      CAUTION:


      • Do not put your hands in the water warmed up during the inspection.

      • Touching the hot water may result in burns.

      Note

      When checking the engine coolant temperature sensor in water, do not allow water to contact the terminals. After completing the check, dry the engine coolant temperature sensor.

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