INSPECTION
1.
Ignition "ON"
2.
Using the multi-tester, Measure resistance between terminal "1" and "2" of water temperature sensor.

Specification

-30 (-22)
177.49 ± 3%
-20 (-4)
97.12 ± 3%
-10 (14)
55.27 ± 3%
0 (32)
32.61 ± 3%
20 (68)
12.48 ± 3%
40 (104)
5.33 ± 3%
60 (140)
2.50 ± 3%
80 (176)
1.27 ± 3%

3.
If the measured resistance is not specification, substitute with a known-good water temperature sensor and check for proper operation.
4.
If the problem is corrected, replace the water temperature sensor.
Negative type thermistor that resistance will rise with lower temperature, and reduce with higher temperature.
REPLACEMENT
1.
Disconnect the negative (-) battery terminal.
2.
Remove the crashpad lower panal(A).

3.
Pull the water temperature sensor out at the heater unit with the clamp (C).

4.
Install in the reverse order of removal.
-
Apply caulk to the water temperature sensor.
-
Make sure that there is no air leakage.
