Description:

This error code, ECU 001075.15, is set when the ECU detects that the fuel pump temperature is higher than expected. Elevated temperatures can indicate an overheating pump, which may result from prolonged operation, insufficient cooling, or internal pump issues.

Reaction:

The ECU may limit or disable the fuel pump to prevent damage due to overheating.

Recommendations:

• Inspect Cooling System: Ensure that the fuel pump and surrounding components have adequate cooling. Check for any obstructions or malfunctions in the cooling system.
• Examine Fuel Pump Operation: Verify that the fuel pump is not operating under excessive load or for prolonged periods without proper cooling intervals.
• Check for Blockages: Inspect the fuel lines and filters for blockages that could cause the pump to work harder and generate excess heat.
• Replace Faulty Pump: If the fuel pump is found to be overheating due to internal issues, replace it with a new one.
• Reset ECU and Conduct Tests: After addressing the overheating issue, reset the ECU to clear the error code and perform tests to ensure that the fuel pump operates within normal temperature ranges.

Note:

Maintaining proper cooling and operating conditions for the fuel pump is essential for preventing overheating and ensuring reliable fuel delivery. Regular inspections and timely maintenance can help prevent such issues.
