CHECKING THE INTAKE AIR
TEMPERATURE SENSOR
1. Remove:
• Intake air temperature sensor
(from the air filter case.)
Refer to “GENERAL CHASSIS” on page 4-1.
EWA14110
• 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 ( 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”.
Make sure that the intake air temperature sensor
terminals 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.
e. Measure the intake air temperature sensor
resistance.

CHECKING THE FUEL INJECTOR
1. Remove:
• Fuel injector
Refer to “THROTTLE BODY” on page 6-9.
2. Check:
• Fuel injector resistance
Out of specification Replace the fuel injec-
tor.
