PTI 524232.04 – Park Brake Pressure Sensor Circuit Voltage Low

PTI 524232.04 (PTI )

Code: 524232.04



This error code is caused by the park brake pressure sensor circuit being open or short to ground. When this code is present, the PTI control unit assumes a pressure of 2100 kPa (21 bar) (305 psi) when the park is released. Park brake pressure can be viewed at PTI Address 023.


The control unit limits the functionality of the equipment to prevent potential damage.


  • Inspect Sensor Circuit:
    • Check the park brake pressure sensor circuit for any open connections or shorts to ground.
    • Repair or replace any damaged wiring or connectors.
  • Test Sensor Voltage:
    • Verify that the voltage levels in the sensor circuit are within the specified range.
    • Replace the pressure sensor if it is found to be faulty.
  • Evaluate Ground Connections:
    • Ensure all ground connections are secure and free of corrosion.


Maintaining proper voltage levels in the sensor circuit is essential for accurate pressure readings and reliable operation.
