Turn the ignition switch OFF.
Remove the ECTS (Refer to "Removal").
After immersing the thermistor of the sensor into engine coolant, measure resistance between the ECTS terminals 3 and 4.
Check that the resistance is within the specification.
Temperature | Resistance (㏀) | |
℃ | ℉ | |
-40 | -40 | 48.14 |
-20 | -4 | 14.13-16.83 |
0 | 32 | 5.79 |
20 | 68 | 2.31-2.59 |
40 | 104 | 1.15 |
60 | 140 | 0.59 |
80 | 176 | 0.32 |
100 | 212 | 0.19 |
110 | 230 | 0.145 ~ 0.149 |
120 | 248 | 0.12 |
Turn the ignition switch OFF and disconnect the battery negative (-) terminal.
Remove the air cleaner.
(Refer to Engine Mechanical System - “Air Cleaner”)
Remove the battery.
(Refer to Engine Electrical System - "Battery")
Disconnect the engine coolant temperature sensor connector.
Remove the engine coolant temperature sensor (A).
Note that engine coolant may flow out from the water temperature control assembly when removing the sensor.
Fill with engine coolant.
(Refer to Engine Mechanical System - "Coolant")
Install the component to the specified torques.
Note that internal damage may occur when the component is dropped. If the component has been dropped, inspect before installing.
Apply the engine coolant to the O-ring.
Carefully insert the sensor into the installation hole without damaging it.
Install in the reverse order of removal.
Engine Coolant Temperature Sensor :
29.4 ~ 39.2 N.m (3.0 ~ 4.0 kgf.m, 21.7 ~ 28.9 lb-ft)
