P0532 GMC code

What the P0532 code means. The voltage for the A/C refrigerant pressure sensor is too low, and the powertrain control module has detected this issue. It stores the code, and once the code is stored, the Check Engine Light will usually illuminate.

How do I test my AC pressure sensor?


Zitat von Youtube: The easiest way to locate the pressure switch is to follow the ac lines coming out of the compressor. The larger line will be your low side pressure switch.

What does a refrigerant pressure sensor do?

The refrigerant is pressurized in the air conditioning system to operate properly, and it is monitored by the refrigerant pressure sensor. This switch, located in a refrigerant line by the firewall, is designed to assess how much pressure is being used in the AC system.

Where is the refrigerant pressure sensor located?

Part of 1 of 1: Replacing the refrigerant pressure sensor



The refrigerant pressure sensor is typically mounted to the A/C pressure line, compressor, or accumulator/drier.

Where is the AC sensor located?

Zitat von Youtube: Which is located inside the dashboard. The evaporator temperature sensor will be located. On or near the evaporator.

  9. What causes high pressure switch on AC?

    The most common cause of a refrigerant high-pressure switch tripping in the wintertime is lack of airflow across the indoor coil. One of the signs of lack of airflow is a high temperature split across the indoor coil. Inspect the filter, not just if it is dirty but restrictive.

    How do I know if my AC pressure switch is bad?

    If the AC is cutting on and off rapidly, unable to cool the cabin, or failing to turn on the compressor, you should replace your AC pressure switch.

    What happens if refrigerant pressure is too low?

    Low refrigerant means low pressure and low pressure means low temperatures that will eventually freeze something called an evaporator coil. When the evaporator coil freezes, cold liquid refrigerant flows through the refrigerant line, causing the surrounding moisture in the air to freeze.
