Description:

ECU 000613.03 is activated when the circuit of fuel pressure control valves is either open or shorted to a 12-volt source, leading to potentially incorrect fuel pressure management.

Reaction:

The ECU may respond by altering fuel delivery parameters, potentially causing engine instability or poor performance.

Recommendations:

• Check Valve Wiring and Circuitry: Inspect wiring for damage or improper connections that could lead to voltage discrepancies.
• Diagnose and Repair Faults: Identify the cause of the high voltage condition and repair any electrical faults in the circuit.
• Ensure Valve Functionality: Test the fuel pressure control valves to ensure they operate within specified parameters after repair.
• Reset ECU to Confirm Repair: Clear diagnostic codes and reset the ECU to ensure the system acknowledges the repair and functions correctly.

Note:

Correct operation of fuel pressure control valves is critical for accurate fuel system management.
