The evaporator temperature sensor acts as a protection device maintaining the evaporator temperature between 34� F and 37� F. These limits could vary depending on the ambient temperature in Automatic temperature control systems. Most of the time, the sensor is located towards the rear of the condenser (or closer to the rear of the vehicle as opposed to the front end). The interior, heat exchanger, evaporator, outside and coolant temperatures are evaluated for the purpose of temperature control together with the driving speed and engine speed signals. 1. If the hvac control module sees the temp going too low, it will send a communication message to the pcm to turn off the a/c compressor until the evap temp returns to an acceptable range. Evaporator sensors Controlling the temperature of the evaporator is one of the most important functions of temperature sensors in air-conditioning systems. Behind the engine compartment and behind the dashboard is where the AC evaporator is located. Note Some engines may have a couple of sensors one sends the engine information to the control unit, the other sends the control unit information to the panel. Another type of thermostatic utilizes a bulb, a capillary tube, and a bellows.

Do a 10 minute bypass and save money Check here for special coupons and promotions. Step 6: Remove the EVAP temperature sensor. The evaporator temperature sensor or switch is a component commonly found on many road going vehicles. Usually on the side of the head. Thermostatic switches are created in different ways. These coils are inside your air conditioner unit. General Diagnosis. 2. Where is the evaporator temperature sensor? The cooler the evaporator, the faster and more efficiently can the passenger compartment be cooled. One popular method utilizes a metal disk that�s bent into the shape of a bowl .As the switch heats or cools, the shape of the bowl changes activating or deactivating the ac compressor. Usually, you can get access to it by simply looking under the dash. The cooler thermistor sensor (evaporator temperature sensor) is installed on the evaporator in the air conditioner unit to detect the temperature of the cooled air that has passed through the evaporator and is used to control the air conditioning. The cabin temperature sensor is used for detecting the average air temperature in the cabin and for allowing an accurate reading; a small fan is used to lead sample air to the sensor.
