Photo sensor
Using a trim stick, remove the photo sensor from the defroster
garnishes.
INSPECTION '
ENGINE COOLANT TEMPERATURE SENSOR CHECK
(1) Dip the engine coolant temperature sensor in hot water
and, using a stove, etc., raise the engine coolant tempera-
ture.
(2) Check that the engine coolant temperature sensor is con-
ductive when the engine coolant temperature reaches
the specified temperature.
Standard value: 26.5 + 4°C (79.7 f 7.2"F)
AIR INLET SENSOR CHECK
The condition can be considered normal if the resistances
are measured within the ranges of 3.98-4.12 kilohms
2.21-2.35 kilohms, respectively, when the air inlet 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 air inlet and the resistance values
is as shown below.
