When is the code detected?

The P0532 code is detected when the signal circuit is too low.

Possible Symptoms

  • Engine Light ON (or Service Engine Soon Warning Light)
  • A/C Inoperative
  • A/C Blows Warm

P0532 Description

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.
