CHECKING THE INTAKE AIR
TEMPERATURE SENSOR
1. Remove:
•
Intake air temperature sensor
(from the air filter case)
WARNING
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.
