Description:

This diagnostic code is generated when the voltage to the second injection valve exceeds normal parameters, indicating a short to 12 volts. This fault can lead to uncontrolled fuel injection, affecting engine operation and efficiency.

Reaction:

The ECU may adjust or limit fuel injection to prevent potential damage or operational hazards due to the high voltage.

Recommendations:

• Inspect Electrical Connections: Check for damaged insulation or improper wiring that could result in a voltage spike.
• Test Voltage Levels: Verify the voltage at the injection valve connector to ensure it aligns with specifications.
• Correct Electrical Faults: Repair any identified issues with wiring or connectors to restore normal voltage levels.
• Reset ECU and Validate Repairs: Resetting the ECU ensures it recognizes the corrected state. Validate the repair with a full operational test of the injection system.

Note:

Correct voltage supply is essential for precise fuel injection control. Monitoring and maintenance of the electrical system help maintain optimal engine performance.
