Evaporator Temperature Sensor (Part 2 Of 2)
Self-diagnosis indicator light D comes on: A problem in the evaporator temperature sensor circuit.
The evaporator temperature sensor is a temperature dependent resistor (thermistor). The resistance of the thermistor decreases as the evaporator outlet air
temperature increases.
CAUTION: The sensor uses a thermistor which can be damaged if high current is applied during testing. Therefore, use a circuit tester with an output
of 1 mA or less at the 20 K Ohms range.
