PTA 522389.04 – Solenoid Valve for Clutch 4, Voltage Too Low

PTA 522389.04 (PTA )

Code: 522389.04



This diagnostic trouble code is generated when the PTA control software detects a voltage value at the solenoid valve for clutch 4 that does not correspond with the switch status of clutch 4, indicating a short to ground or a defective solenoid valve.


Limited or no function of the transmission until the error is corrected, indicating a critical issue with the solenoid valve circuit.


Inspect Solenoid Valve Circuit:

  • Check the circuit for any short circuits to ground.
  • Repair any identified issues in the circuit.

Test Solenoid Valve:

  • Measure the voltage output to the solenoid valve using a multimeter.
  • Replace the solenoid valve if it is producing abnormally low voltage readings.

Examine Wiring and Connectors:

  • Inspect all wiring and connectors associated with the solenoid valve for clutch 4 for signs of damage or corrosion.
  • Repair or replace any damaged components to ensure proper electrical connections.

Ensure Proper Grounding:

  • Verify that the solenoid valve circuit is properly grounded.
  • Correct any grounding issues that may be causing voltage irregularities.


Low voltage readings from the solenoid valve can lead to severe operational problems. Regular inspection and maintenance of the solenoid valve and its circuitry are essential to prevent these issues.
