P0532 on Chevrolet
A/C Refrigerant Pressure Sensor 'A' Circuit Low Input
P0532 on Chevrolet vehicles indicates a/c refrigerant pressure sensor 'a' circuit low input. Au7o has documented this code across 1 Chevrolet model — most commonly on Equinox. P0532 means the control module detected a voltage from the A/C refrigerant pressure sensor that is below the normal range — typically indicating a reading that is too low to be plausible. This sensor measures refrigerant pressure so the computer can engage the compressor safely and control the cooling fans. When the signal is too low, the system often disables the A/C compressor to protect it, so the air conditioning may blow warm or not work. It is not a drivetrain safety issue but affects A/C performance and should be checked. Typical repair costs on Chevrolet range from $400 to $900, depending on the specific model and root cause.
Common Causes of P0532
- •Low refrigerant charge (often from a leak)
- •Faulty A/C refrigerant pressure sensor
- •Short to ground or open in the sensor signal wire
- •Corroded or damaged sensor connector
- •Loss of 5-volt reference to the sensor
- •Poor ground in the sensor circuit
- •PCM/HVAC module fault (less common)
P0532 on Chevrolet by Model
Chevrolet Equinox(1 issue)
- A/C condenser refrigerant leak (warm air from vents)2010-2022
The air-conditioning condenser on the Equinox commonly develops refrigerant leaks at its tubes and seals, or from stone-chip damage to the front-mounted core. Because the condenser's internal tubes and seals cannot be serviced individually, a leak requires full condenser replacement. The classic symptom is the A/C blowing warm air, often with an oily, grimy residue visible on the condenser where refrigerant and PAG oil have escaped. This is a frequently reported wear item across multiple model years, especially 2016-2017.

What does P0532 mean on Chevrolet?▼
P0532 stands for "A/C Refrigerant Pressure Sensor 'A' Circuit Low Input." P0532 means the control module detected a voltage from the A/C refrigerant pressure sensor that is below the normal range — typically indicating a reading that is too low to be plausible. This sensor measures refrigerant pressure so the computer can engage the compressor safely and control the cooling fans. When the signal is too low, the system often disables the A/C compressor to protect it, so the air conditioning may blow warm or not work. It is not a drivetrain safety issue but affects A/C performance and should be checked. On Chevrolet specifically, this code is documented across 1 model.
What causes P0532 on Chevrolet vehicles?▼
Common causes on Chevrolet: Low refrigerant charge (often from a leak), Faulty A/C refrigerant pressure sensor, Short to ground or open in the sensor signal wire, Corroded or damaged sensor connector, Loss of 5-volt reference to the sensor.
