P0530 Fault in the A/C pressure sensor wiring

By: · Updated:

P0530 means: Fault in the A/C pressure sensor wiring. The A/C pressure sensor measures pressure in the air-conditioning system. OK to drive, but have it checked soon. The repair usually costs about €50–250 in Estonia. The most common cause: low refrigerant. Other possible causes: pressure sensor has failed, connector or wire.

What it means

The A/C pressure sensor measures pressure in the air-conditioning system. With this fault the A/C won't switch on.

What could be wrong

  1. 1Low refrigerant
  2. 2Pressure sensor has failed
  3. 3Connector or wire

What you can check yourself

It's fine to drive. The A/C may not work for now. You can check the simple things yourself, but the repair is best done in a workshop.

How we fix it

  1. We check the pressure and the sensor
  2. We recharge the A/C and look for leaks
  3. We replace the sensor

Standard SAE description: A/C Refrigerant Pressure Sensor Circuit
