      (Engine Coolant Temperature Sensor)
      *b Resistance
      *c Temperature
      *d Acceptable Range

      Measure the resistance according to the value(s) in the table below.

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

      Note

      When checking the engine coolant temperature sensor in water, be careful not to allow water to intrude into the terminals. After checking, clean off water on the engine coolant temperature sensor.

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