Conditions for Setting the DTC
WARNING: This page is about a different car, the 2007 Saturn Vue. However, it is still accessible from the selected car via links, so may be relevant.
- The ECM/PCM detects that the A/C pressure is less than 0 psi (0.01 volt).
- The ECM/PCM detects that the A/C pressure is more than 446 psi (4.94 volt).
P0530
- The ECM/PCM detects a too high or too low signal on the A/C refrigerant pressure sensor signal circuit.
- The ECM/PCM has received an A/C request from the BCM over serial data with A/C sensor voltage greater than 4.94 volts (446 psi).
- The ECM/PCM is not receiving an A/C request from the BCM over serial data with A/C refrigerant pressure sensor voltage greater than 4 volts (358 psi).
- Conditions for setting the DTC are met for 15 seconds.
P0532
- The ECM/PCM detects a low signal on the A/C refrigerant pressure sensor signal circuit.
- Conditions for setting the DTC are met for longer than 3 seconds.
P0533
- The ECM/PCM detects a high signal on the A/C refrigerant pressure sensor signal circuit.
- Conditions for setting the DTC are met for longer than 3 seconds.
