Description:

This error code indicates that the resistance in the circuit to the first injection valve is too low, suggesting a short to ground. Such a condition can cause excessive current flow, potentially leading to overheating and damage to the injection valve or associated wiring.

Reaction:

The ECU may restrict engine functions to prevent damage from the short, impacting fuel delivery and engine performance.

Recommendations:

• Inspect Wiring and Connectors: Check the wiring to the injection valve for signs of wear, insulation damage, or contact with ground.
• Measure Circuit Resistance: Use a multimeter to confirm low resistance readings, pinpointing areas of concern.
• Repair or Replace Damaged Wiring: Address any identified shorts by repairing or replacing wires or connectors.
• Reset ECU and Perform System Checks: After repairs, reset the ECU to clear the fault code and conduct tests to ensure the injection system operates correctly under all conditions.

Note:

Maintaining proper electrical integrity in the injection system is crucial for safe and efficient engine operation. Regular inspections can help prevent short circuits and associated damage.
