Description:

Error code ECU 001075.05 is triggered when the ECU detects that the circuit resistance in the fuel pump is too high. This indicates an open circuit, which can prevent the fuel pump from operating correctly, leading to insufficient fuel delivery and potential engine performance problems.

Reaction:

The ECU may limit engine performance to prevent potential damage due to improper fuel pump operation.

Recommendations:

• Inspect Fuel Pump Wiring and Connectors: Check the wiring and connectors leading to the fuel pump for signs of damage, corrosion, or loose connections that could cause an open circuit.
• Measure Circuit Resistance: Use a multimeter to measure the resistance in the fuel pump circuit. High resistance readings confirm an open circuit.
• Repair or Replace Faulty Wiring: Address any identified issues by repairing or replacing damaged wires, connectors, or terminals to restore proper circuit continuity.
• Test Fuel Pump Operation: After repairs, test the fuel pump to ensure it operates correctly and the circuit resistance is within the specified range.
• Reset ECU and Verify Operation: Reset the ECU to clear the error code and conduct tests to confirm that the fuel pump operates correctly and no further errors are detected.

Note:

Maintaining proper wiring and connections for the fuel pump is essential for ensuring reliable fuel delivery and optimal engine performance. Regular inspections and timely repairs can help prevent open circuit issues.
