P0532 code definition

The P0532 code indicates that the input voltage for the A/C refrigerant pressure sensor circuit is too low.

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.

What causes the P0532 code?

The P0532 code can be cause by a number of different things. The following are some of the most common:

What are the symptoms of the P0532 code?

In addition to the engine light coming on in the vehicle, you will notice issues with your air conditioning system. In some cases, it will not operate at all. In other cases, it will only blow warm air. Neither of these options is ideal, so you should make sure you take the vehicle to the mechanic to get diagnosed and repaired as soon as you are able to do so.

How does a mechanic diagnose the P0532 code?

The mechanic wants to get a picture of everything that’s going on with your vehicle. They will hook up an OBD-II scanner to the vehicle, which will communicate with the onboard computer. This scanner will provide the user with data about the codes that are stored and the problems with your car or truck. The information they gather can help to make the diagnosis easier. In addition, if the air conditioner is still running, but this code is present, the mechanics will want to reset the code and drive the vehicle to see if it returns. If it doesn’t return, it may have been tripped by mistake. If it does, it means there are issues with the A/C and more trouble could be around the corner.

Common mistakes when diagnosing the P0532 code

One of the mistakes that is quite common when dealing with the P0532 code, as well as other air conditioning codes, is believing that the problem stems from the lack of refrigerant. It is never a good idea to add refrigerant without first thoroughly testing the system and finding the true cause of the problem. Having too much refrigerant could actually cause catastrophic failure in the system.

How serious is the P0532 code?

Driving around town, to and from work or the store, or anywhere else for that matter is no fun in the heat if you don’t have air conditioning. You do not want to spend any more time than you have to without AC in your vehicle. If you are having issues with your A/C and you have the code stored in your car or truck, you will want to get it taken care of right away.

What repairs can fix the P0532 code?

Let’s look at some of the repairs that can be made by mechanics to fix the P0532 code:

  • Check the refrigerant and add it only if needed
  • Check the cooling fans and repair or replace if needed
  • Replace a faulty A/C refrigerant pressure sensor
  • Check the wiring for open, shorted, and corroded wires, and replace as needed

Additional comments for consideration regarding the P0532 code

Remember that too much refrigerant can be a problem in your air conditioning system. In addition, realize that you need to have the help of professionals when it comes to working on the A/C systems. Take your vehicle to the mechanics so they can provide you with a proper diagnosis and repair.

Rodrigo was exactly on time, very professional and friendly. He assessed my car, let me know the exact problem when a previous mechanic from a shop in my area was unable to. I felt he was very honest and sincere letting me know the level of urgency that I deal with the issue. Absolutely no pressure. I will absolutely use Rodrigo the next time I need anything to do with my car and will tell everyone about him. This is such a great service, I will never go to another mechanic again. It is so convenient. I couldn’t be happier. :)
