Evaporator Temperature Sensor Test
CAUTION:
To avoid damage to sensor, use an ohmmeter with a measuring current of one milliamp or less.
Unplug connector from evaporator temperature sensor. Measure sensor resistance at specified temperatures. See EVAPORATOR TEMPERATURE SENSOR RESISTANCE table. If resistance is not as specified, replace sensor.
