CHECKING THE AIR TEMPERATURE
SENSOR
1. Remove:
• Air temperature sensor
WARNING
EWA3D81003
• Handle the air temperature sensor with
special care.
• Never subject the air temperature sensor to
strong shocks. If the air temperature sen-
sor is dropped, replace it.
2. Check:
• Air temperature sensor resistance
Out of specification → Replace.

a. Connect the pocket tester (Ω × 100) to the air
temperature sensor terminal as shown.
b. Immerse the air temperature sensor “1” in a
container filled with water “2”.
NOTE:
Make sure that the air temperature sensor termi-
nals do not get wet.
c. Place a thermometer “3” in the water.
d. Slowly heat the water, and then let it cool
down to the specified temperature.
e. Measure the air temperature sensor resis-
tance.
