  1. Measure the resistance.

    1. Using an ohmmeter, measure the resistance between the terminals.

      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
      NOTICE:
      When checking the engine coolant temperature sensor in the water, keep the terminals dry. After the check, wipe the sensor dry.
      If the resistance is not as specified, replace the engine coolant temperature sensor.
