WARNING: This page is about a different car, the 2018 Ford Focus. However, it is still accessible from the selected car via links, so may be relevant.

Refer to Automatic Climate Control System for schematic and connector information.

Normal Operation and Fault Conditions 

The A/C pressure transducer receives a ground from the PCM. A 5-volt reference voltage is supplied to the A/C pressure transducer from the PCM. The A/C pressure transducer then sends a voltage to the PCM to indicate the A/C pressure.

DTC Fault Trigger Conditions 

DTC Description Fault Trigger Conditions
P0532 A/C Refrigerant Pressure Sensor A Circuit Low The A/C pressure transducer inputs a feedback voltage to the PCM. This DTC sets if the feedback voltage is lower than expected.
P0533 A/C Refrigerant Pressure Sensor A Circuit High The A/C pressure transducer inputs a feedback voltage to the PCM. This DTC sets if the feedback voltage is greater than expected.
