Are there any sensors located on the evaporator?
The evaporator sensor will either be mounted to the evaporator or the evaporator case. The exact location of the evaporator varies from vehicle to vehicle, but it is generally located inside or underneath the dash. Consult the repair guide for your vehicle to determine the exact location.
How does an evaporator sensor work?
If the sensor detects that the temperature is approaching high temperatures, the AC system increases flow through the system to increase cooling. It reduces flow when it detects that the evaporator is cold to conserve power and prevent it from freezing over.
What does a evaporator temp sensor do?
The evaporator temperature sensor or switch is a component commonly found on many road going vehicles. It is a part of the vehicle’s AC system, and as its name implies, detects and monitors the temperature of the AC system’s evaporator.
How do I know if my EVAP temperature sensor is bad?
Symptoms of a Bad or Failing Evaporator Temperature Sensor (Switch)
- No cold air from the AC system. One of the first symptoms of a potential problem with the evaporator temperature switch is no cold air from the AC system.
- AC temperature fluctuates.
- AC compressor does not activate.
How do you control the evaporator temperature?
In either system operation of the temperature control valve acts to control pressure in the evaporator and thus controls the temperature. With the sensor located in the air stream, the system functions to control the air stream temperature and will compensate the system for frost build-up on the evaporator.
Where is the evaporator temp. sensor located?
The evaporator temperature sensor tells the PCM or ECM the temperature of the evaporator and keeps the evaporator core from freezing .It is usually located inside the hvac case underneath the dash , mounted on the evaporator core.
Where is the EVAP temperature sensor?
And that’s where you can find the A/C Evap Temperature Sensor helpful. Usually located at the evaporator housing, this device is an important part of your A/C system that monitors the temperature in the coldest point of the evaporator.
Where best to place temp sensor?
Temperature / Temperature-Humidity Sensors Mount the sensor vertically at least 6 feet off the ground . Provide good airflow around the sensor. Direct sunlight can inflate the temperature reading, so a north-side, shaded location is best.
Where is the temp sensor located?
The cabin temp sensor is located behind the blank switch plate (or switch, depending on model) by your right knee. There are openings just underneath the switch that you can feel with your fingers. This is where the air temp is sensed.
