Details of the Dodge p0533 OBD Code

Dodge fault code P0533 relates to A/C refrigerant pressure sensor circuit high input.

Dodge OBD code P0533 means that the A/C refrigerant pressure sensor circuit signal is too high.

This code is triggered by the Engine Control Module (ECM) when it detects a voltage signal from the A/C refrigerant pressure sensor that exceeds the specified parameters.

The A/C refrigerant pressure sensor is responsible for monitoring the pressure of the air conditioning system to ensure proper operation and efficiency.

When the signal is too high, it indicates a potential issue with the A/C system’s pressure levels, which can affect the performance of the air conditioning system.
