Outside Air Temperature Sensor
Removal
Remove the screw, disconnect the connector, and
remove the outside air temperature sensor. Be careful
not to damage the front grille and front bumper.
OUTSIDE AIR
TEMPERATURE
SENSOR
Test
Compare the resistance reading between the terminals
of the outside air temperature sensor with specifica-
tions shown in the following graph: It should be within
specification.
NOTE: Dip the sensor in ice water, and measure the
resistance. Then pour hot water on the sensor, and
check for change in resistance.
CAUTION: The sensor uses a thermistor which
can be damaged if high current is applied to it dur-
ing testing. Therefore, use a circuit tester that puts
out a measuring current of 1 mA or less.
