Evaporator temperature sensor reference voltage check
1) Connect connector to HVAC control module with ignition
switch turned OFF.
2) Turn ignition switch to ON position.
3) Measure voltage between signal terminal and ground
terminal of evaporator temperature sensor connector.
Is voltage 4.5 – 5.5 V?
Go to Step 4.
Substitute a known-
good HVAC control
module and recheck.

Evaporator temperature sensor check
1) Check evaporator temperature sensor for performance
referring to “Evaporator Temperature Sensor
Inspection”.
Is it in good condition?
Substitute a known-
good HVAC control
module and recheck.
Replace evaporator
temperature sensor.
