Code result
P0532
A/C Refrigerant Pressure Sensor Circuit Low Input
Moderate severity
What it means
A/C pressure sensor signal voltage below the lower threshold — open, short to ground, sensor fault, or a refrigerant charge so low that the pressure is genuinely low.
Is it safe to drive?
Use caution
The vehicle is usually drivable for short distances, but the problem can worsen or affect emissions. Diagnose and repair as soon as practical.
