11.Intake air temperature sensor resistance
• Remove the intake air temperature sensor
from the air filter case.
• Connect the pocket tester (Ω × 100) to the
intake air temperature sensor terminal as
shown.
Tester positive probe → brown/white 1
Tester negative probe → black/blue 2
• Measure the intake air temperature sensor
resistance.
Intake air temperature sensor
resistance
450 ~ 550 Ω at 20 °C
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.
