CHECKING THE INTAKE AIR
TEMPERATURE SENSOR
1. Remove:
• Intake air temperature sensor
(from the air filter case.)
EWB03820
WARNING
• Handle the intake air temperature sensor
with special care.
• Never subject the intake air temperature
sensor to strong shocks. If the intake air
temperature sensor is dropped, replace it.
2. Check:
▲▲▲
• Intake air temperature sensor resistance
Out of specification → Replace.
▼ ▼▼▼ ▼ ▼▼▼ ▼
a. Connect the pocket tester (Ω × 100) to the in-
take air temperature sensor terminal as
shown.

b. Immerse the intake air temperature sensor
"1" in a container filled with water "2".
TIP
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, then let it cool down to
the specified temperature.
