No
1
1) Turn ignition switch OFF, and then disconnect outside air
temperature sensor connector referring to “Outside Air
Temperature Sensor Removal and Installation”.
2) Turn ignition switch ON, and then check voltage
between “YEL/BLK” wire terminal at outside air
temperature sensor connector and body ground.
Is voltage about 3.5 V?
Go to Step 4.
Go to Step 2.
2
1) Turn ignition switch OFF, and then disconnect HVAC
control module connector referring to “HVAC Control
Module Removal and Installation in Section 7A”.
2) Check resistance between “YEL/BLK” wire terminal at
outside air temperature sensor connector and “YEL/
BLK” wire terminal at HVAC control module connector.
Is resistance less than 1 M
Ω
?
Go to Step 3.
“YEL/BLK” wire open or
high resistance.
3
1) Check resistance between “YEL/BLK” wire terminal and
body ground.
Is resistance more than 1 M
Ω
?
Poor connection of
“YEL/BLK” wire terminal
at HVAC control module
connector, and/or HVAC
control module faulty.
“YEL/BLK” wire shorted
to ground.
