Air Conditioning Refrigerant Pressure Sensor
The Air Conditioning Refrigerant Pressure Sensor For 2013 Gmc Terrain 3.6Litre also known as AC refrigerant pressure switch is a very important component in the climate control system of your 2013 GMC Terrain 3.6L vehicle. It functions by continuously monitoring the pressure of the refrigerant running in the air conditioning system. Because the performance of the AC system is highly dependent on maintaining the correct refrigerant pressure.
This precision pressure transducer employs a strain-gauge sensing element to monitor air conditioner refrigerant pressure with ±0.25% FS accuracy. As freon pressure fluctuates between 50-500 psi, the Wheatstone bridge circuit detects microchanges in electrical resistance (0-5V output), transmitting real-time data to the vehicle’s HVAC control module via CAN 2.0B protocol. The integrated temperature compensation (-40°C to +125°C operational range) ensures reliable freon pressure monitoring across extreme thermal cycling conditions in automotive AC systems.
What happens if the AC pressure sensor goes bad？
ac pressure switch symptoms：
- Poor AC Performance: If the air conditioning refrigerant pressure sensor is malfunctioning, you may notice that the AC system is not cooling as effectively as it should. This can be due to incorrect pressure readings leading to improper compressor operation.
- Warning Lights: A common symptom of a failing sensor is the illumination of the AC warning light on the dashboard. This indicates that the vehicle’s control module has detected an issue with the air conditioning refrigerant pressure sensor a circuit low. OBD-II Trouble Code：P0532.
- Inconsistent Temperature: The cabin temperature may fluctuate, as the sensor is unable to provide accurate feedback to the control module, resulting in inconsistent cooling.
