GM Genuine Parts A/C Refrigerant Pressure Sensors are designed, engineered, and tested to rigorous standards, and are backed by General Motors. These A/C refrigerant pressure sensors monitor the pressure of the refrigerant circuit, while providing pressure data to the Engine Control Module (ECM) or HVAC control head. The ECM or control head can then regulate the compressor and cooling fan operation, helping to maintain system pressure within the programmed parameters. GM Genuine Parts are the true OE parts installed during the production of or validated by General Motors for GM vehicles. Some GM Genuine Parts may have formerly appeared as ACDelco GM Original Equipment (OE).
