What is an evaporator temperature sensor?
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.
What happens when your AC sensor goes out?
If the temperature sensor stops reading the temperature in the evaporator unit, the air conditioner will just continue to blow cool air into the room. This will result in the room becoming too cold, which can lead to higher energy bills and an uncomfortably cold interior.
Where is the temperature sensor located?
Most of the time it is close to the thermostat of the cooling system, or in some cases even inside of it. Note: Some engines may actually have a pair of sensors—one sending information from the engine to the control unit, the other sending information from the control unit to the dash.
Does temperature sensor affect AC?
Inconsistent cooling As the ambient temperature sensor plays a direct role in the automated function of the AC system, when it is having a problem this may interfere with the system’s ability to cool the vehicle.
Where is the cooling fan temperature sensor located?
The Engine Coolant Temperature Sensor can be located in a few places, depending on the vehicle and its manufacturer. It is most often located close to the thermostat of the cooling system or inside of it. The cooling system is located beneath the air intake pipe and behind the right cylinder.
Does coolant temp sensor affect AC?
Inconsistent cooling Another symptom of a bad or failing ambient temperature sensor is inconsistent cooling. As the ambient temperature sensor plays a direct role in the automated function of the AC system, when it is having a problem this may interfere with the system’s ability to cool the vehicle.
Can thermostat affect AC in car?
The thermostat should not affect the A/C compressor blowing cool air. The thermostat regulates the flow of the coolant in your car’s engine and controls when the coolant flows in and out of the motor from the radiator by opening and closing at specific temperatures.
How can you tell if a temperature sensor is bad?
What Signs May Signal Your Coolant Temperature Sensor May Be Failing?
- Poor Fuel Economy.
- Irregular Temperature Readings.
- Black Smoke from Your Exhaust.
- Your Engine is Overheating.
- Your Check Engine Light is On.
