A/C Refrigerant Pressure Sensor Description

This signal is used by the PCM to enable the cooling fans when head pressure reaches a predetermined amount. If a fault is present in the A/C refrigerant pressure sensor circuit, DTC P0530 sets. When the PCM sets a DTC, the A/C compressor clutch will be disabled. If the A/C refrigerant pressure sensor is stuck, refer to the A/C Refrigerant Pressure Sensor Circuit Check.
