Code P1436 2006 Ford Fusion Description

The P1436 diagnostic trouble code (DTC) for a 2006 Ford Fusion indicates an issue with the A/C evaporator air temperature circuit being too low. The A/C evaporator is a key component of the vehicle's air conditioning system, responsible for cooling the air that is circulated inside the cabin. The air temperature sensor in the evaporator helps regulate the temperature of the air being blown into the cabin. When the sensor detects that the air temperature is too low, it triggers the P1436 code.
