Specification Temperature Resistance (kΩ) °C °F -40-4040.
Inspection1.Turn the ignition switch OFF.2.Disconnect the IATS connector.3.Measure resistance between the IATS terminals 3 and 4.4.Check that the resistance is within the specification.
DescriptionThe auto defogging sensor is installed on the front window glass. The sensor judges and sends signal if moisture occurs to blow out wind for defogging. The air conditioner control module receives signal from the sensor and restrains moisture and eliminate defog by controlling the intake actuator, A/C, auto defogging actuator, blower moto
