Evaporator Temperature Sensor / Switch: Testing and Inspection

A/C Evaporator Inlet and Outlet Air Temperature Sensors Inspection

Reference: A/C Evaporator Inlet and Outlet Air Temperature Sensor Removal and Installation:Manual Type




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 inlet air temperature sensor and/or A/C evaporator outlet air temperature sensor.

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