PTP 000123.03 – Clutch Pressure Sensor/Switch Circuit Voltage High

PTP 000123.03 (PTP 123.03)

Code: 000123.03

Shortcode: 123.03


This error code is triggered when the voltage from the clutch pressure sensor to the PTP control unit exceeds 4.9 V. This indicates an issue with the sensor circuit or a possible short to the power supply.


The control unit limits the functionality to protect the system from potential damage due to high voltage readings.


  • Inspect Sensor Wiring:
    Check the wiring and connectors between the clutch pressure sensor and the PTP control unit for any signs of damage, corrosion, or loose connections.
  • Test Sensor Voltage:
    Measure the voltage at the clutch pressure sensor to ensure it is within the specified range. Replace the sensor if it is faulty.
  • Check Power Supply:
    Ensure that the power supply to the sensor is stable and within the correct voltage range.
  • Consult Technical Support:
    If the issue persists, consult technical support or the manufacturer for further assistance.


High voltage issues can lead to incorrect sensor readings and affect clutch operation, so prompt attention to this error is crucial.
