Description:

Error code ECU 001075.12 is triggered when the ECU detects a fault in the fuel circuit of the low-pressure fuel pump. This fault can be caused by a dirty or failed pump, which can impede proper fuel flow and lead to engine performance issues.

Reaction:

The ECU may limit or disable engine function to prevent potential damage due to inadequate fuel supply.

Recommendations:

• Inspect Fuel Pump: Check the low-pressure fuel pump for signs of dirt, debris, or mechanical failure. Clean or replace the pump as necessary.
• Examine Fuel Lines: Inspect the fuel lines for blockages, kinks, or leaks that could affect fuel flow to the pump.
• Test Fuel Pump Operation: Use diagnostic tools to test the functionality of the fuel pump and ensure it is operating within specified parameters.
• Replace Faulty Components: If the fuel pump is found to be defective, replace it with a new one to restore proper fuel flow.
• Reset ECU and Verify Operation: After addressing the issue, reset the ECU to clear the error code and test the engine to ensure that the fuel pump operates correctly and no further errors are detected.

Note:

Maintaining a clean and functional fuel pump is crucial for ensuring reliable fuel delivery and optimal engine performance. Regular inspections and maintenance can help prevent such issues and ensure the engine operates smoothly.
