ECU 000651.18 (ECU 651.18)
Code: 000651.18
Shortcode: 651.18
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.
