Car Ac Compressor Sensor

Air conditioning pressure switches are designed to protect the a c system against pressure that is too high or too low.

Car ac compressor sensor.

In the words of many repairmen an ac compressor is the heart of an ac system. Your carâ s air conditioning system also contains a couple of sensors that manage operation. Bad car ac compressor symptoms. The location of the refrigerant pressure sensor can differ a lot between car models and depending on whether you are going to replace the high or low pressure sensor.

But usually the sensors are most often located in the engine bay or under the front on the ac condenser on the front of the car. Ac compressors endure a lot of stress. Automotive air conditioning system uses an electromagnetic clutch mechanism that engages the compressor to turn the ac unit. There are both high pressure and low pressure switches.

Air conditioning pressure sensors also known as ac switches turn off a car s air conditioning system whenever the refrigerant pressure reaches a lower extreme. This may not turn out to be true all the time as the ac could have failed due to a fault in some other component. Ac compressor is an important part in the car s air conditioning system. Over a certain number of years this stress will wear down the compressor and cause it to eventually malfunction.

The average car today contains a bewildering range of sensors that feed information to various computers to monitor everything from air intake to emissions and engine timing. Having your car s air conditioning go out suddenly can ruin your day fast. Whatever this sensor is you can locate it in the engine bay area. This not only signals the need for a recharge of refrigerant but also saves the compressor from running without the proper lubrication.

To run this compressor the car s engine is directly connected to the pump rotor of the compressor with a belt. Start with locating the sensor as in some cars it can be an ac high pressure switch function and in some a low one. Some vehicles are equipped with just a high pressure switch while others have both. Ac compressor pressure readings their meaning many of us come to a conclusion that if the vehicle s ac fails to blow crisp cool air the cause is a malfunctioning ac compressor.

Incorrect pressure can damage the compressor hoses and other a c system components. Since car air conditioning systems get turned on and off constantly this power fluctuation puts a lot of stress on the compressor. In simple terms an ac compressor is a pump which creates the heat by putting the air conditioning refrigerant under extremely high pressure. To utilize the ac on your car on demand the clutch compressor is activated.
