CHECKING THE INTAKE AIR
TEMPERATURE SENSOR
1. Remove:
• Intake air temperature sensor
(from the air filter case.)
EWA14110
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.
Intake air temperature sensor re-
sistance
5400–6600 Ω@0 °C (5400–6600
Ω@32 °F)
Intake air temperature sensor re-
sistance
290–390 Ω@80 °C (290–390
Ω@176 °F)
