Description:

This error code indicates that the fuel sender output voltage is above the normal operating range, suggesting an open circuit. This could be due to a wiring issue, a faulty fuel sender, or a connection problem within the system.

Reaction:

When this error is detected, the fuel gauge might display inaccurate readings, potentially leading to incorrect fuel level information for the operator.

Recommendations:

• Inspect Wiring and Connections:
  • Check the wiring for any signs of damage, corrosion, or loose connections.
  • Ensure all connectors are properly seated and free of dirt or debris.
• Test the Fuel Sender:
  • Use a multimeter to check the resistance of the fuel sender. Compare the readings to the manufacturer’s specifications.
  • Replace the fuel sender if it is found to be faulty.
• Verify ECU Input:
  • Check the Electronic Control Unit (ECU) inputs for correct voltage levels.
  • Ensure the ECU is functioning correctly and update its software if necessary.

Note:

This code is typically triggered by an electrical issue. Regular inspection and maintenance of the fuel system wiring can help prevent recurrence.
