🟢 Low severity · drivable
Safe to drive, but the A/C may not work correctly until the pressure sensor is fixed.
What P0532 means
The A/C refrigerant pressure sensor is reporting voltage that's too low. This sensor monitors refrigerant pressure so the computer can protect the A/C compressor.
Symptoms
- Check engine light is on
- A/C not cooling properly
- A/C compressor not engaging
Common causes
- most common: Faulty A/C pressure sensor
- common: Low refrigerant charge
- less common: Shorted or damaged wiring
