What is P0532 fault code? A/C Refrigerant Pressure Sensor “A” Circuit Low Input failure description? How to fix the P0532 fault? What are the symptoms and causes for the P0532 fault code
What is the P0532 fault code? What does it all mean?
A P0532 code means that the voltage signal from A/C gas pressure sensor circuit “A” is too low. The powertrain control module, PCM, detects this problem and sets fault code “P0532” and activates check engine light.
The refrigerant pressure sensor’s job is to regulate the driver’s interior temperature. The BCM or ECC Module (Electronic Climate Control Module) monitors the sensor to determine the system pressure. They then activate or deactivate the compressor according to the results. The refrigerant pressure sensor converts system pressure into an electric signal and transmits it the appropriate modules. It typically has 3 wires. The ground wire is the reference wire at 5 volts, while the return signal is at 2 volts. The signal level is 0. If the refrigerant concentration is high, it will cause the signal to increase. Modules compare the signal cable value with the reference 5 volt and instantly calculate the system pressure using this information.
If the PCM or any other modules detect a low electric voltage in the refrigerant-pressure sensor circuit “A”, it sets the P0532 and related fault codes (P0530/P0531 and P0533).
The P0532 fault code can affect vehicles of all makes and models, including but not limited to: Hyundai, Chevrolet Volvo, Dodge, Seat Jaguar, Peugeot Porsche, Ford, Honda, Honda, Honda, Ford, Ford, Honda, Hyundai, Volvo, Volvo, Dodge, Seat, Dodge, Volvo, Dodge, Seat, Jaguar.
What is the P0532 Fault Code and Why Does It Happen?
Here are some reasons why P0532 should be set.
- – Refrigerant levels too low or too high
- – Refrigerant pressure sensor – Short or open circuit
- – A defective or leaking refrigerant sensor (there might be 1 to 4 sensors within the system).
- Fans with defective air conditioners
- – Cables that are damaged, broken, or missing
- – Connectors that are loose, corroded, or defective
- – ECC or BCM problems (Note: This is a rare event, and the fault must been sought elsewhere before any control module can be replaced).
- – PCM related, but rare issues
If the refrigerant level falls below the required level and the air conditioner continues to work normally, then there may be a leak. The refrigerant pressure sensor may be responsible for preventing the compressor clutch’s engagement if the pressure is too high. If the cooling fan is on and the system pressure exceeds the set point, it could be due to a restricted orifice, expansion valve or condenser.
What are the symptoms for P0532 fault code?
When this code is displayed, the most serious problem you’ll encounter is that your air conditioning system doesn’t work. You will also notice that the check engine lamp will be constantly on. The check engine light is not to be worried about but you don’t want to live in extreme heat without air conditioner.
These symptoms may be present in vehicles with code P0532.
- – Illumination for the check engine light
- Air conditioning systems may not cool or operate properly due to erroneous settings.
- – Your air conditioner may not be working properly
How to Fix the P0532 Fault Code
When dealing with P0532 or other codes relating to air conditioners, one of the biggest mistakes is thinking that the problem is due to a lack refrigerant. It’s not a good idea to add refrigerant unless you have thoroughly tested the system and determined the root cause. A high level of refrigerant can lead to system collapse.
There are several repairs that can resolve the P0532 fault code.
- – Checking the refrigerant and, if necessary topping it up
- – Air conditioning fan repair or replacement.
- – Removing the defective refrigerant pressure sensor
- Repairing damaged, broken or short-circuited cables
- Repairing or replacing corroded, burned, loose, and faulty connectors
- – Repair and detection of gas leaks in air conditioners
How Serious Is the P0532 Fault Code
Although an air conditioner problem is not usually considered an emergency, it is worth having the problem checked by a professional. This will prevent any further damage to your cooling system and get your air conditioner running again. If your air conditioner doesn’t work, you might find it difficult to drive in hot temperatures. You don’t want to spend any more time in an air-conditioned environment than is necessary.
