Inspection
1.
Turn the ignition switch OFF.
2.
Disconnect the ECTS connector.
3.
Remove the ECTS (Refer to "Removal").
4.
After immersing the thermistor of the sensor into engine coolant, measure resistance between the ECTS terminals 3 and 4.
5.
Check that the resistance is within the specification.

Specification: Refer to “Specification”

Removal
1.
Turn the ignition switch OFF and disconnect the battery negative (-) cable.
2.
Remove the air cleaner assembly.
(Refer to Engine Mechanical System - "Air Cleaner")
3.
Disconnect the engine coolant temperature sensor connector (A).
4.
Remove the spring clip (B), and then pull the sensor from the water temperature control assembly.
   
Note that engine coolant may be flowed out from the water temperature control assembly when removing the sensor.

5.
Supplement the engine coolant.
(Refer to Engine Mechanical System - "Coolant")

    Description A/C pressure transducer convert the pressure value of high pressure line into voltage value after measure it. By converted voltage value, engine ECU controls cooling fan by operating it high speed or low speed. Engine ECU stop the operation of compressor when the temperature of refrigerant line is so high or so low irregularl
