Evaporator Temperature Sensor / Switch: Testing and Inspection

A/C Evaporator Inlet and Outlet Air Temperature Sensors Inspection
Check resistance between terminals for A/C evaporator inlet air temperature sensor (1) and A/C evaporator outlet air temperature sensor (2).
If measured resistance is out of specification, replace A/C evaporator temperature sensor.




A/C evaporator inlet and outlet air temperature sensors resistance (Sensor Temperature: Resistance)
0 °C (32 °F): 6.4 - 6.9
25 °C (77 °F): 1.8 - 2.2
