Evaporator Temperature Sensor Test

Dip the sensor in ice water, and measure the resistance between its terminals.

Then pour warm water on the sensor, and check for a change in resistance.
Compare the resistance readings with the specifications shown in Fig 2 ; the resistance should be within the specifications.
