In this video, I show you the exact location of the A/C Refrigerant Pressure Sensor (also known as the A/C pressure switch) on a 2016-2019 Chevrolet Cruze equipped with the 1.4L turbocharged engine. Finding exactly where this sensor is on the vehicle is an essential first step for a quick and clean DIY diagnosis, saving you time and guesswork before you disconnect any electrical plugs.
Common symptoms of a faulty A/C Refrigerant Pressure Sensor include:
- Your air conditioning suddenly stops blowing cold air or refuses to turn on at all, even though the A/C button on your dash is illuminated.
- The A/C compressor clutch fails to engage, or it rapidly cycles on and off every few seconds, preventing the cabin from cooling down.
- An active Check Engine Light (CEL) or body control codes on your dashboard, often accompanied by your engine cooling fans running on high speed constantly as a failsafe measure.
Safety First: The air conditioning system operates under very high pressure. Never attempt to remove or loosen the pressure sensor while the system is under charge unless you are certain the service port’s internal Schrader valve is holding, or the system has been professionally recovered. Always protect your hands and eyes by wearing durable gloves and safety glasses, and stay fully focused and attentive throughout the entire process.
