Compressor Solenoid Valve

The compressor solenoid valve is integral with the A/C compressor. Operation of the solenoid valve is controlled by the ECM using a Pulse Width Modulated (PWM) signal of differing values. By controlling the flow of refrigerant (displacement) through the compressor, the solenoid valve can control evaporator operating temperature and cabin humidity by varying the pressure within the A/C system.
