PTA 523917.08 – Hydrostatic Speed Sensor, Speed at Channel 2 Lower Than at Channel 1

PTA 523917.08 (PTA )

Code: 523917.08

Shortcode:

Description:

This diagnostic trouble code is generated when the PTA control software detects a difference in frequency between the two sensor output signals for hydrostatic speed, indicating that the speed at channel 2 is lower than at channel 1.

Reaction:

Limited or no function of the transmission until the error is corrected, indicating a critical issue with the hydrostatic speed sensors.

Recommendations:

Compare Sensor Signals:

  • Verify the output signals of both channels to ensure consistency.
  • Replace the sensor if there is a significant discrepancy between the two channels.

Inspect Wiring and Connectors:

  • Check the wiring and connectors of both channels for signs of damage or disconnection.
  • Repair or replace any faulty components.

Ensure Proper Calibration:

  • Verify that both channels are properly calibrated to provide accurate speed readings.
  • Recalibrate if necessary.

Monitor Vehicle Conditions:

  • Ensure the vehicle is not operating under conditions that could cause abnormal speed variations.

Note:

Accurate synchronization between the two sensor channels is essential for proper transmission operation. Regular monitoring and maintenance of sensors and their circuits can help prevent synchronization issues.
