PTA 524107.05 – Proportional Solenoid Valve 2 for Hydrostatic Unit, Current Too Low
PTA 524107.05 (PTA )
Code: 524107.05
Shortcode:
Description:
This diagnostic trouble code is generated when the PTA control software registers a current value at the proportional solenoid valve 2 that does not correspond with the commanded working position of the hydrostatic unit. This indicates that the circuit of the proportional solenoid valve 2 is open. If diagnostic trouble code PTA 524108.05 is also stored, a general problem with the supply voltage (VPS1) of proportional solenoid valves 1 and 2 is indicated.
Reaction:
Limited or no function of the transmission until the error is corrected, indicating a critical issue with the solenoid valve circuit.
Recommendations:
Inspect Solenoid Valve Circuit:
- Check the circuit for any open connections or breaks.
- Repair any identified issues in the circuit.
Test Proportional Solenoid Valve:
- Measure the current flow to the solenoid valve using a multimeter.
- Replace the solenoid valve if it is not drawing the correct current.
Examine Wiring and Connectors:
- Inspect all wiring and connectors associated with the solenoid valve for signs of damage or disconnection.
- 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 low current flow.
Check Supply Voltage (VPS1):
- If diagnostic trouble code PTA 524108.05 is also stored, investigate the supply voltage (VPS1) for issues.
- Ensure VPS1 is providing stable voltage to both solenoid valves.
Note:
Low current 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.
