Description:

This error code is generated when the ECU control software cannot determine the engine speed and, as a result, cannot provide the CAN bus with any data. A replacement value is transmitted, generating this diagnostic trouble code in the PTF control software. This fault also generates a diagnostic trouble code in the ECU control software, which takes priority.

Reaction:

When this code is detected, the control software may exhibit limited or no functionality.

Recommendations:

• Inspect Engine Speed Sensor:
  • Verify the functionality of the engine speed sensor using diagnostic tools.
  • Replace the sensor if it is found to be faulty.
• Check Sensor Wiring:
  • Inspect the wiring and connections to the engine speed sensor for damage or loose connections.
  • Repair or replace any defective components.
• Update ECU Software:
  • Ensure the ECU control software is up to date.
  • Update the software if necessary.
• Verify CAN Bus Communication:
  • Use diagnostic tools to ensure that the engine speed data is correctly transmitted over the CAN bus.

Note:

Maintaining a functional engine speed sensor and reliable CAN bus communication is crucial for the control software’s performance. Regular checks and timely replacements can prevent these issues.
