INTERIOR TEMPERATURE SENSOR CHECK

When the resistance between the sensor terminals is mea-
sured under two or more temperature conditions, the resis-
tance should approximately satisfy the illustrated values.

NOTE: 

The temperature conditions when checking should not 

exceed the range shown in the diagram.

.

PHOTO SENSOR CHECK

1. Connect diagnostic tool , and check the data list of the 

photo sensor. (Refer to 

P.55-133

)

2. Check that the displayed value changes when you cover 

the photo sensor with your hands.

AMBIENT AIR TEMPERATURE SENSOR CHECK

CAUTION

The ambient air temperature sensor should be checked 
without removing it from bumper. If the sensor is removed, 
damage will occur to clip rendering it unserviceable.
Measure the resistance between the sensor terminals under at 
least two temperatures. The resistance values should meet the 
values shown.

NOTE: The temperature should be within the shown range.
