P0533 Honda Code - A/C Pressure Sensor Circuit High Voltage

Quick Answer

The A/C Pressure Sensor measures the change in the pressure of the air conditioning refrigerant. Common causes include Faulty A/C Refrigerant Pressure Sensor, A/C Refrigerant Pressure Sensor circuit open or shorted, A/C Refrigerant Pressure Sensor circuit poor electrical connection. Severity is Low - monitor the vehicle and repair when practical. The vehicle can usually be driven if no severe symptoms are present, but symptoms should be checked before extended driving.

Code P0533 Honda Description

The A/C Pressure Sensor measures the change in the pressure of the air conditioning refrigerant. The signal from the A/C Pressure Sensor is low voltage at low pressure (when the air conditioning load is low) and high voltage at high pressure (when the air conditioning load is high). The Powertrain Control Module (PCM) compares the expected voltage to the A/C Pressure Sensor output voltage. When the A/C Pressure Sensor output voltage is lower or higher than the expected voltage for a set time, the PCM detects a malfunction and stores a Diagnostic Trouble Code (DTC). The DTC will be set when the A/C Pressure Sensor output voltage is 4.76 V or more for at least 10 seconds.
