What does a refrigerant pressure sensor do?
The refrigerant is pressurized in the air conditioning system to operate properly, and it is monitored by the refrigerant pressure sensor. This switch, located in a refrigerant line by the firewall, is designed to assess how much pressure is being used in the AC system.
How much does it cost to replace AC pressure sensor?
The average cost for air conditioning refrigerant pressure sensor replacement is between $254 and $271. Labor costs are estimated between $66 and $84 while parts are priced at $187. This range does not include taxes and fees, and does not factor in your specific vehicle or unique location.
How do I know if my AC pressure switch is bad?
If the AC is cutting on and off rapidly, unable to cool the cabin, or failing to turn on the compressor, you should replace your AC pressure switch.

How do you know if your car is low on refrigerant?
- Your A/C is Blowing Warm Air. One of the most obvious symptoms of low Freon levels is if your air conditioner is blowing warm or room temperature air.

What is the most common reason for low refrigerant charge?
Low refrigerant usually occurs because of leaks along the line or in the compressor. Because refrigerant usually evaporates as it escapes, you won’t notice any dripping. Instead, the first sign you’ll see of the loss of refrigerant will be frost over the indoor coils.
