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.
DescriptionThe evaporator temperature sensor will detect the evaporator core temperature and interrupt compressor relay power in order to prevent evaporator from freezing by excessive cooling. The evaporator temperature sensor has the Negative Temperature Coefficient (NTC).
Inspection1.Turn the ignition switch OFF.2.Disconnect the intake actuator connector.3.Verify that the intake actuator operates to the fresh position when connecting 12V to terminal 3 and grounding terminal 4.Verify that the intake actuator operates to the recirculation position when connected in reverse.
