    1. Partially immerse the sensor in water and warm up the water.

    2. 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 engine coolant temperature sensor dry.

      Tech Tips

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