    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 k to 2.59 k Ω
        1 - 2 80 °C (176°F) 0.310 k to 0.326 k Ω
        NOTE:

        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.
