After immersing the thermistor of the sensor into engine coolant, measure resistance between ECTS terminals 1 and 3.
Turn ignition switch OFF.
Disconnect ECTS connector.
Remove the ECTS.
After immersing the thermistor of the sensor into engine coolant, measure resistance between ECTS terminals 1 and 3.
Check that the resistance is within the specification.

-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 ignition switch OFF and disconnect the battery negative (-) terminal.
Remove the Battery.
(Refer to Engine Electrical System - "Battery")
Disconnect the engine coolant temperature sensor connector.
Removal the water temperature sensor (A).
Note that engine coolant may be flowed out from the water temperature control assembly when removing the sensor.
Supplement the engine coolant (Refer to “Cooling System” in EM group).
Install the component with the specified torques.
Note that internal damage may occur when the component is dropped. In this case, use it after inspecting.
Apply the engine coolant to the O-ring.
Insert the sensor in the installation hole and be careful not to damage when installation.
Installation is reverse of removal.
Engine coolant temperature sensor installation:
19.6 - 39.2 N.m (2.0 - 4.0 kgf.m, 14.4 - 28.9 lb-ft)
