      (Engine Coolant Temperature Sensor)

      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
      1 - 2 Approx. 80°C (176°F) 0.310 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 sensor dry.
