Description:

This error code, ECU 001075.06, is set when the ECU detects that the circuit resistance in the fuel pump is too low, indicating a short to ground. This condition can cause the fuel pump to malfunction, leading to insufficient fuel delivery and potential engine performance issues.

Reaction:

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

Recommendations:

• Inspect for Short Circuits: Check the wiring and connectors for the fuel pump for signs of short circuits to ground. Look for damaged insulation, frayed wires, or loose connections.
• Measure Circuit Resistance: Use diagnostic tools to measure the resistance in the fuel pump circuit and identify the location of the short. Low resistance readings confirm a short circuit.
• Repair or Replace Damaged Wiring: Fix any identified short circuits by repairing or replacing faulty wiring, connectors, or terminals. Ensure all connections are secure and properly insulated.
• Verify Fuel Pump Operation: After repairs, test the fuel pump to ensure it functions correctly and the short circuit issue is resolved.
• Reset ECU and Conduct System Tests: Reset the ECU to clear the error code and perform tests to confirm that the fuel pump operates correctly and no further errors are detected.

Note:

Proper maintenance of the fuel pump wiring and connections is essential to avoid short circuits and ensure reliable fuel delivery. Regular inspections and timely repairs can help maintain the integrity of the fuel system.
