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.
