Car Ac Pressure Sensor

Incorrect pressure can damage the compressor hoses and other a c system components.

Car ac pressure sensor.

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. The ac pressure switch plays such an important role in the operation of the ac system and yet is at the same time a component that is quite vulnerable to damage. Some vehicles are equipped with just a high pressure switch while others have both. This protects the compressor from damage.

The most ideal pressure readings are around 150 high and 30 low. Refrigerant does not wear out or evaporate. Learn more about how the car s air conditioning system works here. You might have to do some repairs by yourself to make it run correctly again.

The air conditioning system in a car is actually a pretty complex system and it works based on 2 basic principles. Remember venting 134a refrigerant into our atmosphere is illegal and bad for our environment. An automotive air conditioner s pressure switch cycles the vehicle s compressor on and off when the refrigerant pressure falls below an acceptable level. A tire pressure sensor is a small programmable electronic device located in the pressurized pocket made by a wheel and tire that constantly measures the air pressure inside the tire.

This not only signals the need for a recharge of refrigerant but also saves the compressor from running without the proper lubrication. If the ac. Ac splits into two halves one is low pressure half and the other is high pressure and both sides are equipped with an ac pressure switch. There are both high pressure and low pressure switches.

One might wonder how to jump 3 wire ac pressure switch by own. The following table presents the possible inferences and the actions that can be taken based on the level of pressure registered by the high and low pressure gauges. 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. The ac runs perfectly but you cannot control it with the button.

Ac systems in vehicles run with a pressure switch. 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. Only leaking air conditioning systems have low refrigerant levels. Air conditioning pressure switches are designed to protect the a c system against pressure that is too high or too low.
