  1. Measure the resistance according to the value(s) in the table below.

    Standard Resistance:
    Condition
    		Specified Condition
    Approximately 20°C (68°F)
    		2.32 to 2.59 kΩ
    Approximately 80°C (176°F)
    		0.310 to 0.326 kΩ
    NOTICE:
    When checking the engine coolant temperature sensor in water, keep the terminals dry. After the check, dry the sensor.
    If the resistance is not as specified, replace the engine coolant temperature sensor.
