Evaporator Temperature Sensor / Switch: Testing and Inspection

EVAPORATOR TEMPERATURE SENSOR

INSPECTION
1. Ignition " ON".
2. A/C switch ON.
3. Disconnect evaporator temperature sensor connector.

Specification:

4. Using the multi-tester, Measure resistance between terminal "1" and "2" of evaporator temperature sensor.
5. If the measured resistance is not specification, substitute with a known-good evaporator temperature sensor and check for proper operation.
6. If the problem is corrected, replace the evaporator temperature sensor.
