Specification Temperature Resistance (kΩ) °C °F -40-4048.
Inspection1.Turn the ignition switch OFF.2.Remove the ECTS.(Refer to "Removal")3.After immersing the thermistor of the sensor into engine coolant, measure resistance between the ECTS terminals 1 and 3.
Description The photo sensor is located at the center of the defrost nozzles.The photo sensor contains a photovoltaic (sensitive to sunlight) diode. The solar radiation received by its light receiving portion, generates an electromotive force in proportion to the amount of radiation received which is transferred to the automatic temperature control
DescriptionThe temperature control actuator is located at the heater unit. It regulates the temperature by the procedure as follows. The signal from the control unit adjusts the position of the temperature door by operating the temperature switch. Then the temperature will be regulated by the hot/cold air ratio decided by the position of the temper
