PTQ 524230.06 – Proportional Solenoid Valve for Transmission Enable, Current Too High

PTQ 524230.06 (PTQ )

Code: 524230.06



This diagnostic trouble code, PTQ 524230.06, indicates that the circuit current for the proportional solenoid valve for transmission enable is too high, suggesting a short to ground.


When this error is detected, the control software shifts the transmission into neutral to prevent potential damage.


Inspect Electrical Connections:

  • Check the wiring and connectors associated with the proportional solenoid valve for transmission enable.
  • Ensure all connections are secure and free of shorts or damage.

Test Solenoid Valve:

  • Use a multimeter to measure the current at the solenoid valve signal input.
  • Replace the solenoid valve if it is found to be defective.

Verify Circuit Integrity:

  • Inspect the circuit for any signs of shorted connections or damaged wires.
  • Repair or replace any identified issues to ensure proper current flow.

Update Software:

  • Verify that the control software is up-to-date with the latest version.
  • Update the software if there are any available updates to improve system accuracy and error handling.

Monitor System Performance:

  • After addressing the above steps, test the proportional solenoid valve to ensure proper functionality.
  • Confirm that the current at the signal input is within the specified range during operation.


  • Regular inspection and maintenance of the solenoid valve’s electrical components can prevent high current issues.
  • If the issue persists despite taking the above measures, consult technical support or the manufacturer for further assistance.
