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 kΩ
25 °C (77 °F): 1.8 – 2.2 kΩ
