DTC P0533: - A/C Refrigerant Pressure Sensor A Circuit High

DTC P0533: - A/C REFRIGERANT PRESSURE SENSOR A CIRCUIT HIGH

Description:	The air conditioning pressure (ACP) transducer sensor inputs a voltage to the powertrain control module (PCM). If the voltage is above a calibrated level the DTC sets.
Possible Causes:	ACP transducer sensor circuit short to PWR Open ACP transducer sensor circuit ACP transducer sensor circuit short to VREF Damaged ACP transducer sensor
Diagnostic Aids:	Verify the VREF voltage is between 4 and 6 volts.
Application	Key On Engine Off	Key On Engine Running	Continuous Memory
