P0530 OBD Code Description:

OBD2 Code P0530 Definition:
The powertrain control module (PCM) monitors the high side refrigerant pressure via a A/C refrigerant pressure sensor. When the pressure is high the signal voltage is high. When the pressure is low the signal voltage is low. When pressure is high the PCM commands the cooling fans on. When pressure is too high or too low the PCM will not allow the A/C compressor clutch to engage. Symptoms

Possible sumptoms of P0530
– Engine Light ON (or Service Engine Soon Warning Light) – A/C Inoperative – A/C Blows Warm Possible Causes

Possible causes of P0530
– A/C system low or over charge with refrigerant – Faulty A/C refrigerant pressure sensor – Cooling fans in-operative – A/C refrigerant pressure sensor circuit open or shorted The Error code is generally activated on detection of the following conditions: The P0530 code is detected when the signal circuit is less than 5 counts (0.09 volt) or more than 250 counts (4.90 volts) and the condition exists for 20 seconds.
