Complete List of John Deere PTH Error Codes / PTH Fault Codes

John Deere PTH fault codes, also known as John Deere PTH diagnostic trouble codes or John Deere PTH error codes, are crucial indicators of your equipment’s condition and performance. These codes help pinpoint and fix issues in the Power Train Hydrostatic (PTH) control system.

Where do these codes appear?

These codes show up on the control display of John Deere equipment when the system detects anomalies or faults in components like control pedals, temperature sensors, cooling systems, and other vital parts.

5 Most Common John Deere PTH Fault Codes:

1. PTH 000091.03 – Throttle Sensor Input Voltage Above Normal, or Shorted to High Source

Description: The throttle sensor input voltage is above the normal range or shorted to a high power source.
Where it appears: Throttle control system.

2. PTH 000158.00 – Switch Battery Potential Data Valid but Above Normal Operation Range – Most Severe Level

Description: The battery voltage is above the normal operating range.
Where it appears: Battery and alternator control system.

3. PTH 000630.14 – Calibration Memory Special Instructions

Description: The application software found invalid EEPROM parameters in the PTH.
Where it appears: PTH calibration and memory system.

4. PTH 523590.13 – Machine Drive Forward Pedal Out of Calibration

Description: The forward pedal sensor is out of calibration.
Where it appears: Forward pedal control system.

5. PTH 523591.08 – Machine Drive Reverse Pedal Abnormal Frequency or Pulse Width or Period

Description: The reverse pedal channel signal is missing or has an abnormal update rate.
Where it appears: Reverse pedal control system.

How to Fix These Issues:

Check Sensors and Switches:
- Verify the correct operation and connection of sensors.
- Check for damage or wear.
Diagnose the Power Train Hydrostatic Control Unit (PTH):
- Run diagnostic tests to identify faults.
- Ensure all electrical connections are secure and free from corrosion.
Inspect Wiring and Connections:
- Check the wiring harnesses for damage and loose connections.
- Repair or replace damaged wiring as needed.
Update Control Software:
- Make sure the control unit software is up-to-date with the latest updates and improvements.

Using John Deere PTH fault codes and promptly addressing identified issues helps maintain your equipment’s functionality and efficiency. Regular checks and maintenance of key control system components can prevent major breakdowns and extend the lifespan of your machinery.
