P0532 is set when the voltage below 180mV - minimum voltage of A/C refrigerant pressure sensor signal - is detected for more than 0.6 sec. This code is due to open in power circuit or short to ground in signal circuit of A/C refrigerant pressure sensor.
Item | Detecting Condition | Possible Cause | |
DTC Strategy |
•
Signal monitoring | 1. A/C refrigerant pressure sensor power circuit is open. 2. A/C refrigerant pressure sensor signal circuit is short to ground. 3. Faulty A/C refrigerant pressure sensor. | |
