INSPECTION
WATER TEMPERATURE SENSOR
(1) Dip the water-temperature sensor in hot water and, using a
stove, etc., raise the water temperature.
(2) Check that the water-temperature sensor is conductive
when the water temperature reaches the specified temper-
ature.
Standard value: 26.5 4°C (79.7
OUTSIDE-AIR-TEMPERATURE SENSOR
The condition can be considered normal if the resistances are
measured within the ranges of 3.98 4.12 kilohms and 2.21
2.35 kilohms, respectively, when the outside-air-temperature
sensor is submerged in warm water of 25°C (77°F) and 40°C
(104°F) for one minute or longer each.
NOTE
The relationship between the outside-air-temperature and the
resistance values is as shown below.
