WATER TEMPERATURE SENSOR
1. Measure:
Water temperature sensor resistance
(at the specified temperature)
Out of specification → Replace.
Water temperature sensor
resistance:
0 ˚C (32 ˚F): 24.0 ~ 37.1 kΩ
100 ˚C (212 ˚F): 0.87 ~ 1.18 kΩ
200 ˚C (392 ˚F): 0.104 ~ 0.153 kΩ
Measurement steps:
Ice the water temperature sensor and
measure the resistance.
Suspend the water temperature sen-
sor in a container filled with oil.
Slowly heat the oil.
Measure the resistance when the spec-
ified temperature is reached.
