    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 k to 2.59 kΩ

      1 - 2

      Approx. 80°C (176°F)

      0.310 k 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.

      Tip:

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