Description:

This error code is triggered when the PTP control unit does not detect countershaft speed for 5 seconds while the engine is running and the transmission is in gear. This indicates a potential issue with the countershaft speed sensor.

Reaction:

No action is taken by the control unit.

Recommendations:

• Inspect Speed Sensor:
  Check the countershaft speed sensor for proper operation. Ensure it is securely mounted and free from damage or debris.
• Check Wiring and Connections:
  Inspect the wiring and connectors for any signs of damage, loose connections, or corrosion. Repair or replace as necessary.
• Test Sensor Output:
  Use diagnostic tools to verify that the speed sensor is generating the correct output signals.
• Consult Technical Support:
  If the issue persists, consult technical support or the manufacturer for further assistance.

Note:

A functioning countershaft speed sensor is crucial for accurate transmission control and diagnostics. Regular inspections can help prevent sensor-related issues.
