A/C Refrigerant Pressure Sensor Chevrolet Equinox 2.4L 2010-2017 Location and Replacement

In this video, I show you only the exact location of the A/C Refrigerant Pressure Sensor (also known as the A/C Pressure Switch) on a 2010-2017 Chevrolet Equinox 2.4L.

Knowing the precise spot where this sensor is threaded into the air conditioning lines will save you time and eliminate the guesswork when planning your DIY repair.

Common Symptoms of a Bad A/C Refrigerant Pressure Sensor:

• The A/C compressor clutch fails to engage, causing the system to blow only warm air
• The air conditioning works intermittently (cooling fine one moment, then cutting out the next)
• The engine cooling fans run constantly at maximum high speed, even when the engine is cold
• The A/C light on the dashboard climate controls flashes and turns off when pressed
• The check engine light or body control codes turn on (frequently flagging codes like P0532 or P0533)

Safety First

Always prioritize safety when working near A/C lines and moving engine parts. Make sure the vehicle is safely parked on a flat surface, the engine is completely turned off, and the keys are out of the ignition. Allow the engine compartment plenty of time to cool down fully to avoid painful burns. Protect your eyes and hands by wearing safety glasses and durable work gloves, and always maintain your full focus throughout the task.

Important Service Note: The A/C pressure sensor on this vehicle is installed on a Schrader valve, which allows you to unthread and replace the sensor without discharging or losing the refrigerant. However, if the valve is damaged or leaking, the system must be professionally evacuated first.
