PTA 000191.00 – Sensor for Transmission Output Speed, Speed Too High

PTA 000191.00 (PTA 191.00)

Code: 000191.00

Shortcode: 191.00

Description:

This diagnostic trouble code is generated when the PTA control software detects that the transmission output speed is too high. This can occur when the tractor rolls down an incline in neutral, causing an increased speed range.

Reaction:

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

Recommendations:

Reduce Ground Speed:

  • Immediately reduce the ground speed to prevent damage to the transmission.

Inspect Output Speed Sensor:

  • Verify that the transmission output speed sensor is functioning correctly.
  • Replace the sensor if it is found to be faulty.

Check Sensor Calibration:

  • Ensure the sensor is properly calibrated to provide accurate speed readings.
  • Recalibrate if necessary.

Monitor Vehicle Operation:

  • Avoid operating the vehicle in conditions that may cause it to exceed safe speed limits, such as rolling down steep inclines in neutral.

Note:

Regular monitoring of transmission output speed and adherence to safe operating conditions are crucial to prevent excessive speed issues. Promptly address any sensor or calibration problems to maintain optimal transmission performance.
