Evaporator Temperature Sensor / Switch: Testing and Inspection

INSPECTION

1. Ignition "ON".
2. A/C switch "ON".
3. Using the multi-tester, Measure resistance between terminal "1" and "2" of evaporator temperature sensor.
Specification









4. If the measured resistance is not specification, substitute with a known-good evaporator temperature sensor and check for proper operation.
5. If the problem is corrected, replace the evaporator temperature sensor.
