What Is An Evaporator Temperature Sensor?

Your car’s air conditioner works by removing heat to cool your cabin. Part of this evaporator unit that controls the temperature of your car and expansion valve is the evaporator temperature sensor. Mounted onto the evaporator, it prevents frost from accumulating on your evaporator core and ensures it never freezes over.

Common Signs And Symptoms That You Need to Replace A Evaporator Temperature Sensor

• Air conditioning does not work
• Air conditioning temperature fluctuates without you changing the valve
• Frost creates a “no flow” effect within the evaporator

How Important Is This Service?

Air conditioning is not only valuable to keeping you cool, but for defogging windows. Though it is not dangerous in most cases to drive without air conditioning, we still recommend you have to replaced before your friend’s start melting in your car.
