Description:

This error code, ECU 000651.18, is set when the ECU detects that the fuel flow from injection valve 1 is lower than expected. This condition can lead to improper fuel delivery and engine performance issues.

Reaction:

The ECU may adjust engine parameters or limit performance to compensate for the reduced fuel flow and prevent engine damage.

Recommendations:

  • Inspect Injector for Blockages: Check injection valve 1 for any blockages or debris that might restrict fuel flow.
  • Test Injector Operation: Use diagnostic tools to test the injector’s operation and ensure it is functioning correctly.
  • Verify Fuel Supply: Ensure that the fuel supply to the injector is adequate and that there are no restrictions in the fuel line.
  • Replace Faulty Injector: If the injector is found to be defective, replace it with a new one to restore proper fuel flow.
  • Reset ECU and Conduct System Tests: After addressing the issue, reset the ECU and perform tests to ensure the injector operates correctly and no further errors are detected.

Note:

Maintaining proper injector function is essential for consistent engine performance and efficiency. Regular inspection and maintenance can help prevent such issues.
