Table Of Contents

    Description of DTC code P0532 Generic

    The Refrigerant Pressure Sensor (RPS) helps the HVAC (Ventilation, Heating, and Air Conditioning) system regulate the vehicle’s internal temperature as needed. This sensor converts the refrigerant system pressure into an analog electrical signal. This is done via three wires.

    OBDII DTC P0532 indicates that the input voltage for the RPS Sensor circuit is excessively below the established limit.
