In this video, I show you the exact location of the A/C Refrigerant Pressure Sensor (sometimes called the A/C pressure switch) on a 2012-2016 Chevrolet Malibu 2.5L. Finding exactly where this sensor is threaded into the high-pressure air conditioning line is an essential first step for a smooth DIY vehicle repair, saving you time and preventing unnecessary searching under the hood.
Common symptoms of a faulty A/C Refrigerant Pressure Sensor include:
- Your air conditioning suddenly stops blowing cold air, or the A/C compressor clutch refuses to engage at all.
- The cabin climate control system blows cold air intermittently, or the A/C system cuts out completely under acceleration.
- An active Check Engine Light (CEL) or HVAC trouble codes stored in the computer, along with radiator cooling fans running at high speed continuously even when the engine is cool.
Safety First: The automotive air conditioning system operates under very high pressure. Always protect your hands and eyes by wearing durable gloves and safety glasses, ensure the engine is completely off before disconnecting electrical components, and stay fully focused and attentive throughout the process.
