- Bad connector or corrosion
- Faulty PCM input
How to fix P0530
- Read the A/C pressure value on a scan tool
- Compare the electrical reading to manifold gauge pressure
- Check the sensor wiring and connector
- Verify refrigerant charge if pressure is implausible
- Replace the sensor after confirming circuit and pressure are correct
