PTD 000127.03 – Transmission Pressure Sensor Voltage Too High

PTD 000127.03 (PTD 127.03)

Code: 000127.03

Shortcode: 127.03

Description:

This DTC is generated when the control software detects that the voltage at the signal input of the transmission pressure sensor is too high, indicating a potential short circuit. This issue can also occur if the hydraulic oil filter is restricted at low temperatures.

Reaction:

When this error is detected, the control software may limit or completely disable the transmission functions to prevent damage.

Recommendations:

Check Electrical Connections:

  • Inspect the wiring and connections to the transmission pressure sensor for signs of short circuits or damage.
  • Repair or replace any damaged wiring.

Hydraulic Oil Filter:

  • Check the hydraulic oil filter for restrictions, especially at low temperatures.
  • Replace the filter if it is clogged or dirty.

Sensor Testing:

  • Test the transmission pressure sensor to ensure it is providing accurate voltage readings.
  • Replace the sensor if it is found to be defective.

Consult Technical Support:

  • If the issue is not resolved, consult technical support or a qualified technician for further diagnosis and repair.

Monitor System:

  • After addressing the issue, monitor the sensor voltage to ensure it remains within the specified range.

Note:

Ensuring that the hydraulic system is clean and free from contaminants can help prevent sensor voltage issues. Regularly check and replace filters as needed to maintain proper system function.
